United Airlines experiences yet another major computer glitch

A massive computer outage at United Airlines early Thursday stranded passengers across the country.A spokesperson for United tells WGN-TV that the airline is up and running again.

United Airlines, just a week before the year's busiest travel period, experienced yet another major computer problem Thursday morning that delayed hundreds of flights across the country, mostly on the East Coast. Some airline industry observers called for "heads to roll" at the world's largest airline.

The latest glitch involved the dispatch system software that enables Chicago-based United to communicate with airplanes before departure, delivering information on the plane's weight and balance, number of passengers and baggage, said United spokesman Charlie Hobart.

Flights of United's regional jet service, United Express, were not affected.

The outage occurred from about 7:30 to 9:30 a.m. Thursday and resulted in 257 delays directly attributable to the outage and more through the day, along with about 10 cancellations. The airline said it had 636 delays Thursday, far more than its typical number of about 300. The delays affected a relatively small number of the airline's 5,500 daily flights — fewer than 5 percent, Hobart said.

The impact at O'Hare International Airport seemed to be minimal, United and airport officials said.

United has had rampant problems with an unrelated system, its passenger reservation system it switched to in March. In August, the airline had another unrelated network outage that occurred when a piece of communication equipment in a United data center failed and disabled communications with airports and the United website, United.com. That was due to a failure at a United vendor.

The computer problems, especially the reservation system problem that affected flights in midsummer, have had Jeff Smisek, CEO of United's parent company, United Continental Holdings, making public apologies since March. He conceded to Wall Street analysts that operational problems hurt the airline's third-quarter profits as many customers fled to competitors. But he said during an earnings call with analysts in late October that those problems were behind the airline and that he was confident United would perform well during the busy holiday travel season.

Aside from weather-related delays, such as superstorm Sandy and a snowstorm on the East Coast, that seemed true until Thursday's outage. Even on Thursday, United's on-time performance was about 80 percent, meeting its target, a spokesman said.

"It was a software issue that we found and fixed in that two-hour period," United spokesman Rahsaan Johnson said. "It will not happen again."

Hobart said he did not have details about what went wrong.

Joe Brancatelli, a business travel writer at JoeSentMe.com, said the failures point to a larger problem.

Some industry observers said United is out of excuses.

"It is flat-out unacceptable," said Henry Harteveldt, co-founder of Atmosphere Research Group. "This makes United a laughingstock among airlines."

He said airline computer systems are complex and Thursday's problem might be a one-time issue, but the repeated failures are not only embarrassing for United, they "undermine trust in the airline" and "demoralize employees."

"There are clearly failures in the airline's strategy and the airline's execution, and heads need to roll," he said. "United's (chief information officer) should resign or be dismissed."

Hobart said the airline has improved recently.

"Since this summer, we've significantly improved our operational performance, with nearly 85 percent of our flights on time so far this month and nearly 80 percent of flights arriving on time in October, despite operational challenges like Hurricane Sandy," he said. "We understand this outage was frustrating for our customers, and we are enabling them to rebook without penalty and receive a full refund if their flights were delayed by at least two hours."

"Mostly what it says is that (airlines) have got to stop looking at mergers as two route maps you can smash together," Brancatelli said. He contends that the United-Continental merger was not planned properly.

"There are too many things going wrong," he said. Blame rests with "the guys running the show," he said of United's top executives. "The fish stinks from the head."

RIM CEO sees new BlackBerry powering growth

WATERLOO, Ontario (Reuters) – A new line of BlackBerry 10 devices will provide Research In Motion with a framework for growth over the next decade, offering long-term value for unhappy shareholders, Chief Executive Thorsten Heins said on Wednesday.

In an interview with Reuters, Heins said RIM had identified $ 800 million of the $ 1 billion of savings it promised for the financial year ending in early March, and was confident of finding the rest as it gets ready to launch the new phones.

RIM is betting that the new smartphones will help it claw back the market share it has lost to the likes of Apple Inc’s iPhone and devices powered by Google’s Android operating system.

Both consumers and corporate customers have abandoned the BlackBerry in droves, even though the devices offer security features that rivals have been unable to match.

“There’s this high-level security that you cannot walk away from, and then there’s ‘good enough’ security,” Heins said in an interview at RIM’s Waterloo, Ontario, campus, a sprawl of low-rise buildings.

But analysts remain skeptical, especially after the botched 2011 launch of RIM’s PlayBook tablet computer, which the company had hoped would compete with Apple’s wildly popular iPad. The PlayBook had top-of-the-line hardware, but its software was far from complete at the launch and needed multiple updates.

RIM delayed the roll-out of the BlackBerry 10 phones to the first quarter of 2013 so as not to repeat the errors that surrounded the PlayBook launch.

Heins said the delay was the correct decision – the way to ensure the BB10 phones are a high-quality product rather than a rushed one that would not meet customer expectations.

“I think it’s all lining up. Sometimes you get the feeling that the universe is in disarray, and with BlackBerry 10 coming, I see the stars lining up,” Heins said.

SLEEK DEMO MODELS

Sleek demo models of the new phones look much like the high-end smartphones in the market today, and company executives proudly showed off a touch-screen version and a version with the miniature QWERTY keyboard popular with many BlackBerry users.

Users flick a thumb or finger to maneuver from one program to another and can sneak a look at an incoming email while browsing the Internet or using other applications, a multi-tasking ability that RIM says rival devices lack.

Personal and business profiles can be kept separately, something RIM calls BlackBerry Balance. Corporations can erase only their share of the data on a device if they need to do so for security reasons, leaving personal photos, contacts and emails untouched.

The app library available at launch will not match the vast number available on other devices. Heins said RIM had chosen to focus on providing those apps needed in different regional markets. It expects some 100,000 apps to be ready at launch.

The developer community has been broadly enthusiastic about the devices. But financial analysts have mixed views on their likely reception in an ultra-competitive market.

Pacific Crest analyst James Faucette warned last week that BlackBerry 10 is likely to be dead on arrival – with an operating system that gets “a lukewarm response at best,” due to the unfamiliar user interface and a shortage of apps.

SHAREHOLDER VALUE

Heins insisted morale was high at the company, despite 5,000 job cuts and a rapidly sliding market share ahead of the launch of the new phones.

RIM’s share price is down more than 90 percent from a 2008 peak of about $ 148. It has fallen even after Heins, a former Siemens AG executive, took over in January. The shares on Wednesday closed at $ 8.49 on Nasdaq.

“The message to our shareholders is that we understand this is and has been a difficult time for them and for us,” the tall, bespectacled CEO said. “But with the development of the BlackBerry 10 platform we are truly convinced that we will create long-term value for RIM’s shareholders and investors.”

RIM has already given the demo phones to developers and to carriers, and its new BlackBerry Enterprise Server 10, which runs the devices on corporate networks, is in beta testing with 20 key customers — both government agencies and corporates.

Next month, the company will give more than 50 top enterprise customers technical previews of both BES 10 and the devices.

Heins said the feedback he is getting from the customer base “is very encouraging.”

With the erosion of RIM’s base particularly strong in North America, there has been speculation the company could choose to launch the new phones in a region where the phones remain popular. Heins said that would not be the case.

“We cannot launch every carrier and every country on the same day, but what we have defined is a set of waves in the various regions,” he said. “It is going to be a global launch. There isn’t one preferred region. We are managing and planning it as we speak.”

Judge throws out Justin Bieber paparazzo chase case

LOS ANGELES (Reuters) – Criminal charges filed against a photographer who pursued teen pop star Justin Bieber at high speeds on a Los Angeles freeway in July were thrown out on Wednesday, striking a blow to California’s crackdown on overly aggressive paparazzi.

Celebrity photographer Paul Raef was the first person to be prosecuted under the state’s 2010 law that criminalizes dangerous driving when taking photos commercially.

Raef was charged in July with two counts of violating the law stemming from a July 6 incident on a freeway in Los Angeles‘ San Fernando Valley.

Dismissing the charges, Los Angeles Superior Court Judge Thomas Robinson called the state’s anti-paparazzi law “problematic” and “overly inclusive.”

The law “sweeps very widely and would increase the penalties for reckless driving” in unintended cases, Robinson said.

Robinson faulted the law’s vague definition of commercial photography, saying that it could also apply to a photographer who was speeding to reach an arranged photo shoot with Bieber.

Raef could have faced up to a year in prison and $ 3,500 in fines, if convicted. His attorney, Brad Kaiserman, said the law is “about protecting celebrities.”

A message left with Bieber’s publicist requesting comment was not immediately returned.

Raef still faces lesser charges of misdemeanor reckless driving and failing to obey police orders after he allegedly pursued Bieber, 18, at high speeds. He will be tried on those charges at a later date.

Bieber, who was pulled over by police for driving 80 miles per hour in a 65 mph zone, told officers at the time that he was being hounded by paparazzi, and police said they noticed Raef’s car following the “Boyfriend” singer.

About 30 minutes after the traffic stop, Bieber called police to report that Raef continued to follow him. Police later found Raef and other paparazzi together in downtown Los Angeles.

The Canadian singer received a speeding ticket at the time.

Alzheimer’s Tied to Mutation Harming Immune Response

Alzheimer’s researchers and drug companies have for years concentrated on one hallmark of Alzheimer’s disease: the production of toxic shards of a protein that accumulate in plaques on the brain.

But now, in a surprising coincidence, two groups of researchers working from entirely different starting points have converged on a mutated gene involved in another aspect of Alzheimer’s disease: the immune system’s role in protecting against the disease. The mutation is suspected of interfering with the brain’s ability to prevent the buildup of plaque.

The discovery, researchers say, provides clues to how and why the disease progresses. The gene, known as TREM2, is only the second found to increase Alzheimer’s risk substantially in older people.

“It points very specifically to a potential metabolic pathway that you could intervene in to change the course of Alzheimer’s disease,” said William Thies, chief medical and scientific officer of the Alzheimer’s Association.

Much work remains to be done before scientists understand precisely how the newly discovered gene mutation leads to Alzheimer’s, but already there are some indications from studies in mice. When the gene is not mutated, white blood cells in the brain spring into action, gobbling up and eliminating the plaque-forming toxic protein, beta amyloid. As a result, Alzheimer’s can be staved off or averted.

But when the gene is mutated, the brain’s white blood cells are hobbled, making them less effective in their attack on beta amyloid.

People with the mutated gene have a threefold to fivefold increase in the likelihood of developing Alzheimer’s disease in old age.

The intact gene, says John Hardy of University College London, “is a safety net.” And those with the mutation, he adds, “are living life without a safety net.” Dr. Hardy is lead author of one of the papers.

The discovery also suggests that a new type of drug could be developed to enhance the gene’s activity, perhaps allowing the brain’s white blood cells to do their work.

“The field is in desperate need of new therapeutic agents,” said Alison Goate, an Alzheimer’s researcher at Washington University in St. Louis who contributed data to Dr. Hardy’s study. “This will give us an alternative approach.”

The fact that two research groups converged on the same gene gives experts confidence in the findings. Both studies were published online Wednesday in The New England Journal of Medicine. “Together they make a good case that this really is an Alzheimer’s gene,” said Gerard Schellenberg, an Alzheimer’s researcher at the University of Pennsylvania who was not involved with the work.

The other gene found to raise the odds that a person will get Alzheimer’s, ApoE4, is much more common and confers about the same risk as the mutated version of TREM2. But it is still not clear why ApoE4, discovered in 1993, makes Alzheimer’s more likely.

Because the mutations in the newly discovered gene are rare, occurring in no more than 2 percent of Alzheimer’s patients, it makes no sense to start screening people for them, Dr. Thies said. Instead, the discovery provides new clues to the workings of Alzheimer’s disease.

To find the gene, a research group led by Dr. Kari Stefansson of deCODE Genetics of Iceland started with a simple question.

“We asked, ‘Can we find anything in the genome that separates those who are admitted to nursing homes before the age of 75 and those who are still living at home at 85?’ ” he said.

Scientists searched the genomes of 2,261 Icelanders and zeroed in on TREM2. Mutations in that gene were more common among people with Alzheimer’s, as well as those who did not have an Alzheimer’s diagnosis but who had memory problems and might be on their way to developing Alzheimer’s.

The researchers confirmed their results by looking for the gene in people with and without Alzheimer’s in populations studied at Emory University, as well as in Norway, the Netherlands and Germany.

The TREM2 connection surprised Dr. Stefansson. Although researchers have long noticed that the brain is inflamed in Alzheimer’s patients, he had dismissed inflammation as a major factor in the disease.

“I was of the opinion that the immune system would play a fairly small role, if any, in Alzheimer’s disease,” Dr. Stefansson said. “This discovery cured me of that bias.”

Meanwhile, Dr. Hardy and Rita Guerreiro at University College London, along with Andrew Singleton at the National Institute on Aging, were intrigued by a strange, rare disease. Only a few patients had been identified, but their symptoms were striking. They had crumbling bones and an unusual dementia, sclerosing leukoencephalopathy.

“It’s a weird disease,” Dr. Hardy said.

He saw one patient in her 30s whose brain disease manifested in sexually inappropriate behavior. Also, her bones kept breaking. The disease was caused by mutations that disabled both the copy of TREM2 that she had inherited from her mother and the one from her father.

Eventually the researchers searched for people who had a mutation in just one copy of TREM2. To their surprise, it turned out that these people were likely to have Alzheimer’s disease.

They then asked researchers around the world who had genetic data from people with and without Alzheimer’s to look for TREM2 mutations.

“Sure enough, they had good evidence,” Dr. Hardy said. The mutations occurred in one-half of 1 percent of the general population but in 1 to 2 percent of patients with Alzheimer’s disease.

“That is a big effect,” Dr. Hardy said.

FCC recommends cross-ownership waivers for Tribune Co.

The staff of the Federal Communications Commission has recommended that the agency grant Tribune Co. waivers of so-called media ownership rules, paving the way for the company to emerge from its long-running bankruptcy.

The waivers -- the last major hurdle in the four-year case -- would take effect Friday as long as none of the five commissioners raise serious objections, according to a person at the FCC who wasn't authorized to speak and therefore did not want to be identified.

No vote is required for the waivers to take effect.

The waivers would set the wheels in motion to emerge from bankruptcy, something that can happen as soon as new ownership, a group led by senior creditors Oaktree Capital Management, Angelo Gordon & Co and JPMorgan Chase & Co., can complete the necessary paperwork.

The FCC staff is recommending that the agency grant a permanent waiver to Tribune's ownership of the Chicago Tribune and WGN radio and television stations and that it give  one-year waivers for the Los Angeles Times ownership of KTLA-TV Channel 5 and for similar arrangements in three other markets.

The FCC also is circulating among commissioners a proposal for new media ownership rules that would ease restrictions on consolidations among newspapers and TV and ratio stations, according to FCC Chairman Julius Genachowski. That proposal is expected to come up for an agency vote at the next regular meeting.

Once the new rules are in effect, Tribune's new owners could seek permanent waivers in the Los Angeles, New York, Hartford, Conn., and South Florida markets.

Tribune Vice President Shaun Sheehan declined to comment.

Hastert uses government office for private business

A Tribune investigation has found that former U.S. House Speaker Dennis Hastert has used his taxpayer-funded office to conduct private business. Federal law allows former House speakers to maintain a government-financed office for up to five years, but they are not permitted to use the office for financial gain. (Nuccio DiNuzzo, Chicago Tribune / November 14, 2012)

By Katherine Skiba and Todd Lighty




Tribune reporters

11:55 p.m. CST, November 13, 2012

Former U.S. House Speaker J. Dennis Hastert has conducted private business ventures through a little-known government office that has cost taxpayers about $1.8 million, a Tribune investigation has found.

Former House speakers are allowed to maintain a government-financed office for up to five years to wrap up matters relating to their tenure. They are not permitted to use the office for financial gain.

But the Tribune found that a secretary in the ex-speaker’s government office used email to coordinate some of his private business meetings and travel, and conducted research on one proposed venture. A suburban Chicago businessman who was involved in the business ventures with Hastert said he met with Hastert at least three times in the government office to discuss the projects.

Hastert, an Illinois Republican, said he did not misuse the office. “I didn’t work on any private business out of there,” he said.

Court records, interviews and dozens of emails link the Office of the Former Speaker to J. David John, a Burr Ridge businessman who made six of the emails public in a lawsuit in DuPage County. John alleges in his suit that Wheaton College officials and others ruined his business relationship with Hastert, who is not a defendant in the suit.

She’s got the voice, now Christina Aguilera looks for hits

LOS ANGELES (Reuters) – Christina Aguilera has the vocal chops, the look, the strut and millions of new fans thanks to her stint as a judge on TV singing contest “The Voice.”

But can she still sell records?

The singer, who had global hits with “Genie in a Bottle” and the female empowerment ballad “Beautiful” more than 10 years ago, bids to reclaim her status as one of the world’s biggest pop stars with her new album, “Lotus,” released on Tuesday.

Aguilera, 31, says the title and the mixture of dance-pop, ballads and rock-tinged tracks reflect the hopes and disappointments of recent years that saw her 2010 tour for album “Bionic” canceled, a divorce and the box-office flop of her debut feature film, the musical “Burlesque.”

“Lotus represents the unbreakable flower that stands the test of time. No matter the roughest of weather conditions, it remains strong and continues to thrive. (The album) is a nod to my fans who have been here with me the whole journey, and a nod to myself,” she said.

“It is a record of freedom and embracing that…It is very artistic at times, it is very fun at times, it is very free. I think that’s how music and life should be, away from all the negativity,” the four-time Grammy winner said in an appearance at a Billboard Film and TV Music conference in Los Angeles last month.

Aguilera will perform one of the tracks – “Make the World Move” – with her fellow judge Cee Lo Green live on “The Voice” this week for the show’s more than 10 million viewers.

But music industry experts say Aguilera’s popularity on “The Voice” – where her powerhouse performances leave aspiring pop stars in the dust – may not guarantee huge album sales and won’t give the singer a No. 1 hit.

This week also sees new releases from British boy band One Direction and singer Susan Boyle as well as the new “Twilight” film soundtrack.

NOT A BLOCKBUSTER

“I think ‘Lotus’ will certainly debut in the top 10 on the Billboard 200 album chart. But we don’t see it as being a blockbuster out of the gate,” said Keith Caulfield, associate director of charts at Billboard.

“It is a long road to rebuilding Christina as a brand and as a musician, after the last album didn’t so very well,” said Caulfield. “But it’s not always about first week sales.”

Much like Jennifer Lopez on “American Idol,” Aguilera has seen her star rocket in her 18 months on “The Voice.” Just a few months before the TV show made its debut in spring 2011, Aguilera was arrested for being drunk in public in West Hollywood, and her 2010 album “Bionic” had sold a disappointing 312,000 copies.

“‘The Voice’ has reinvigorated her entire career. A lot of people think she is the star of ‘The Voice’ – the judge you tune in for,” said Lyndsey Parker, managing editor at Yahoo! Music.

Yet the first single – “Your Body” – from the new album failed to make a big impact when it was released in September. It peaked at No. 34 on the Billboard Hot 100 chart and never really caught fire on radio.

“It came and went, which surprised me because I think it is a very strong song. And pretty much everything I have heard on this album is strong. I think it’s a real return to form,” said Parker.

“There are very few people in pop who can sing like her. I do think there is a renewed appreciation for great singing that can be done live and that isn’t just about flash. And Christina is coming back to prove that. I think some people are looking at her to take back her crown,” Parker added.

“Lotus” includes duets with both Green and Aguilera’s fellow “Voice” judge, country singer Blake Shelton. It also features the piano-driven ballad “Blank Page,” which is reminiscent of her 2002 hit “Beautiful” and rock-tinged tracks like “Army of Me.”

Aguilera says she hopes to inspire a new generation of singers who were not around in 1999 for her first big hit “Genie in a Bottle.”

“It’s so exciting for me to show them what I do as an artist,” she said. “I’ve been through a lot over the past few years, going through ‘Burlesque,’ a divorce…having a few setbacks….Stuff happens! This is the business. It’s not going to be all cute and pretty and tied up in a bow.

“All of that combined is in ‘Lotus.’ It embraces the woman that I’ve become, and embracing myself coming full circle as a pop star,” she said.

‘Dream Team’ of Behavioral Scientists Advised Obama Campaign

Chris Keane/Reuters

DOOR TO DOOR Ricky Hall, an Obama volunteer, in Charlotte, N.C., last week.

Late last year Matthew Barzun, an official with the Obama campaign, called Craig Fox, a psychologist in Los Angeles, and invited him to a political planning meeting in Chicago, according to two people who attended the session.

“He said, ‘Bring the whole group; let’s hear what you have to say,’ ” recalled Dr. Fox, a behavioral economist at the University of California, Los Angeles.

So began an effort by a team of social scientists to help their favored candidate in the 2012 presidential election. Some members of the team had consulted with the Obama campaign in the 2008 cycle, but the meeting in January signaled a different direction.

“The culture of the campaign had changed,” Dr. Fox said. “Before then I felt like we had to sell ourselves; this time there was a real hunger for our ideas.”

This election season the Obama campaign won a reputation for drawing on the tools of social science. The book “The Victory Lab,” by Sasha Issenberg, and news reports have portrayed an operation that ran its own experiment and, among other efforts, consulted with the Analyst Institute, a Washington voter research group established in 2007 by union officials and their allies to help Democratic candidates.

Less well known is that the Obama campaign also had a panel of unpaid academic advisers. The group — which calls itself the “consortium of behavioral scientists,” or COBS — provided ideas on how to counter false rumors, like one that President Obama is a Muslim. It suggested how to characterize the Republican opponent, Mitt Romney, in advertisements. It also delivered research-based advice on how to mobilize voters.

“In the way it used research, this was a campaign like no other,” said Todd Rogers, a psychologist at Harvard’s Kennedy School of Government and a former director of the Analyst Institute. “It’s a big change for a culture that historically has relied on consultants, experts and gurulike intuition.”

When asked about the outside psychologists, the Obama campaign would neither confirm nor deny a relationship with them. “This campaign was built on the energy, enthusiasm and ingenuity of thousands of grass-roots supporters and our staff in the states and in Chicago,” said Adam Fetcher, a campaign spokesman. “Throughout the campaign we saw an outpouring of individuals across the country who lent a wide variety of ideas and input to our efforts to get the president re-elected.”

For their part, consortium members said they did nothing more than pass on research-based ideas, in e-mails and conference calls. They said they could talk only in general terms about the research, because they had signed nondisclosure agreements with the campaign.

In addition to Dr. Fox, the consortium included Susan T. Fiske of Princeton University; Samuel L. Popkin of the University of California, San Diego; Robert Cialdini, a professor emeritus at Arizona State University; Richard H. Thaler, a professor of behavioral science and economics at the University of Chicago’s business school; and Michael Morris, a psychologist at Columbia.

“A kind of dream team, in my opinion,” Dr. Fox said.

He said that the ideas the team proposed were “little things that can make a difference” in people’s behavior.

For example, Dr. Fiske’s research has shown that when deciding on a candidate, people generally focus on two elements: competence and warmth. “A candidate wants to make sure to score high on both dimensions,” Dr. Fiske said in an interview. “You can’t just run on the idea that everyone wants to have a beer with you; some people care a whole lot about competence.”

Mr. Romney was recognized as a competent businessman, polling found. But he was often portrayed in opposition ads as distant, unable to relate to the problems of ordinary people.

When it comes to countering rumors, psychologists have found that the best strategy is not to deny the charge (“I am not a flip-flopper”) but to affirm a competing notion. “The denial works in the short term; but in the long term people remember only the association, like ‘Obama and Muslim,’ ” said Dr. Fox, of the persistent false rumor.

The president’s team affirmed that he is a Christian.

At least some of the consortium’s proposals seemed to have found their way into daily operations. Campaign volunteers who knocked on doors last week in swing states like Pennsylvania, Ohio and Nevada did not merely remind people to vote and arrange for rides to the polls. Rather, they worked from a script, using subtle motivational techniques that research has shown can prompt people to take action.

“We used the scripts more as a guide,” said Sarah Weinstein, 18, a Columbia freshman who traveled with a group to Cleveland the weekend before the election. “The actual language we used was invested in the individual person.”

This article has been revised to reflect the following correction:

Correction: November 14, 2012

An article on Tuesday about the role of social scientists in President Obama’s re-election campaign omitted a word from the title of the book by Sasha Issenberg that examines data-driven campaign strategies. The book is “The Victory Lab,”  not “Victory Lab.”

Microsoft executive exits at a shaky time

Turns out Microsoft Corp.'s radical overhaul of its Windows operating system last month wasn't the only big change in store for the company.

The abrupt departure of Steven Sinofsky, president of Windows and Windows Live, is being called poor timing for the tech behemoth. It's also seen as a sign that longtime Chief Executive Steve Ballmer has no plans to step down anytime soon.

Sinofsky's exit, just weeks after the company rolled out the Windows 8 operating system, "doesn't necessarily reflect well on the company," said Kirk Materne, managing director at Evercore Partners.

"I think if you're Steve, having this happen right after creates a level of distraction that you don't want in the first place," he said. "It's never great when you've had this much turnover at the senior level of a company that is really trying to gain its footing in markets like tablet and mobile."

Shares of Microsoft slid 90 cents, or 3.2%, to $27.09 on Tuesday. Its stock has languished in the last decade — virtually unchanged — while shares of rival Apple Inc. have climbed more than 6,700%.

Microsoft is under pressure to impress consumers and investors with its latest offerings, which include Windows 8 and its new Surface device, a hybrid tablet-laptop that launched last month.

But both products have been met with lackluster interest. Windows 8 debuted to low investor expectations, and reviews for the revamped operating system have been mixed, with some users saying it's at times confusing to use.

The Surface, meanwhile, was buzz-worthy when it was first unveiled, but analysts seem unconvinced that it will make a dent in a market currently dominated by Apple's iPad. Although the hardware is sleek, the Surface lacks applications compared with the iPad, and its highly touted snap-on keyboard that doubles as a cover is difficult to accurately type on, reviewers have said.

The Windows 8 launch was said to be the biggest revamp of the operating system in nearly two decades. The latest update includes a new interface called the Start screen that was designed for tablets and touch-screen computers and features moving tiles similar to those on Windows Phone devices. Microsoft wants the new Start screen interface to be the future of Windows.

"The general conclusion of Win 8 is on the surface, it's a solid first start," Materne said. "It's not mind-blowing, it's not going to immediately recapture market share, but it gets them back in the ballgame to a certain degree."

Sinofsky, a 23-year Microsoft veteran, was in charge of the Windows 8 and Surface efforts at the Redmond, Wash., company. He was a polarizing figure in the office with a tough management style and was rumored to be in line to succeed Ballmer, who has been chief executive since 2000.

In an employee memo Monday, the day Microsoft announced his departure, Sinofsky said he had decided to leave to seek "new opportunities."

"With the general availability of Windows 8/RT and Surface, I have decided it is time for me to take a step back from my responsibilities at Microsoft," he said. "I've always advocated using the break between product cycles as an opportunity to reflect and to look ahead, and that applies to me too."

Now that Sinofsky has left, analysts — some of whom speculated there had been a rift between Sinofsky and Ballmer — say they expect a new direction for the Windows division.

"Sinofsky was a highly talented operator who hit product release dates, got delivery in Windows to be more reliable, and was pivotal to successful Office and Win 7 releases," Morgan Stanley analyst Adam Holt said in a note to investors. "While he is a loss for Microsoft, Windows has entered a different phase where cultivation of developers, collaboration between product groups, integration with the mobile operating system and a focus on applications become more important."

Sinofsky will be replaced by Julie Larson-Green, who has been with the company since 1993 and oversaw program management, user interface design and research for Windows 7 and 8. She will lead all Windows software and hardware engineering.

Tami Reller, Windows chief financial officer and chief marketing officer, also will assume responsibility for the business of Windows.

There could be a bit of a learning curve in the meantime, said equity analyst Angelo Zino of S&P Capital IQ.

"We are surprised by the announcement, given Sinofsky's recent success as well as a belief by many that he could eventually have been the successor to CEO Steve Ballmer," he said. "While we are confident in the abilities of both individuals, we see the change increasing product development risk to future Windows releases."
