 LAS VEGAS Microsoft kicked off the International Consumer Electronics Show (CES)  Monday night here much as the company has done since its first CES  keynote in 1998 extolling the virtues of Windows and promising big  things from its operating system in the future. But with the recent rise  of smart phones and tablets that run competitive operating systems from Apple and Google,  Microsoft has increasingly been on the defensive, forced to distinguish  itself from technologies that seem to have leapfrogged Windows in  relevance.
LAS VEGAS Microsoft kicked off the International Consumer Electronics Show (CES)  Monday night here much as the company has done since its first CES  keynote in 1998 extolling the virtues of Windows and promising big  things from its operating system in the future. But with the recent rise  of smart phones and tablets that run competitive operating systems from Apple and Google,  Microsoft has increasingly been on the defensive, forced to distinguish  itself from technologies that seem to have leapfrogged Windows in  relevance.In what was to be the company’s final CES keynote, Ballmer, joined by American Idol  host Ryan Seacrest and several Microsoft colleagues, promoted the  success of Windows 7 both on desktops and mobile devices and provided  new details on its upcoming Windows 8. The latest version of the  operating system, which developers have been able to tinker with since  September, will run across a variety of gadgets, including mobile  phones, PCs and the emerging “ultrabooks” category of thinner, lightweight laptops.
Windows 8 will roll out to  consumers throughout the year as computer and phone makers introduce  their latest Windows devices to the market. Ballmer called Windows 8 a  “reimagination” of Microsoft’s flagship operating system. Indeed, it  will support wireless devices that use low-power ARM microprocessors  designed specifically to improve mobile gadget battery life in addition  to the standard processors from Intel and AMD that Windows has  supported for years.
Another key Windows 8 feature is its “Start Screen” interface that  enables it to be used on touch-screen devices such as tablets as well as  mouse-and-keyboard PCs. 
Based on Microsoft’s demo, the Windows 8  operating system shares the look and feel of iOS and Android, which  offer apps that take users directly to functions such as e-mail, the Web  and sites such as Facebook and Twitter.Computer makers are showing strong support for Windows 8: Acer, Asus,  Dell, HP, Lenovo, Samsung and Sony are just some of the companies  introducing new computers that will use the operating system. And by the  end of February, Microsoft will open a Windows app store it hopes will  rival online shops already offered by Apple and Google.
The question for Microsoft is  whether the PC platform itself will continue to dominate. Tablets such  as Apple’s iPad, Samsung’s Galaxy and even Amazon’s relatively  low-priced Kindle Fire are becoming increasingly popular for capturing  and viewing video, managing e-mail and a variety of other tasks that  once required PCs. Smart phones such as the iPhone and a growing number  of Google Android-based handsets can likewise replicate a number of PC  functions, with the exception of the Windows bread-and-butter Word,  PowerPoint and Excel applications.
In step with the software  upgrades, Microsoft refuses to concede the smart phone market. It has  been making a play there with the Windows Phone  version of its operating system, and the company last year launched a  partnership with Nokia. During his keynote, Ballmer introduced the first  Nokia handsets to run Windows Phone, including the 4G Nokia Lumia 900  operating on the AT&T LTE network. Ballmer likewise showed off a new  Windows Phone from HTC that features a 16-megapixel camera. Both smart  phones will be available by the end of the year.
Despite the shiny hardware,  Ballmer’s keynote served to show just how difficult it is to distinguish  products in today’s smart phone market. Some Windows phones feature  front-facing cameras for mobile video calls and voice-activated  controls, but these features are already available on the iPhone and  several Android phones.
More impressive than Microsoft’s almost obligatory enhancements in  mobile computing and smart phones was the company’s plans for its Xbox  video game system and Kinect motion-sensing technology. Microsoft  continues to transform Xbox beyond gaming into a full-fledged online  entertainment and social-networking system for televisions. Kinect will  also enable “two-way” television, letting people  interact directly with  TV programs. This was demonstrated through Kinect Sesame Street TV, a  special version of the popular children’s program. During the demo, a  girl onstage used the Kinect sensor to toss virtual coconuts onscreen to  the Muppet Grover and also to dance with Elmo.
Microsoft expects two-way television to be available by the end of the year. Interactive TV isn’t a new concept IBM was talking about this at least 20 years ago,  for example. Yet the success of Microsoft’s Kinect motion-sensing  technology thus far gives this particular prognostication some  credibility.
Suspicious for its absence in Ballmer’s presentation was much talk of Microsoft’s recent $8.5-billion acquisition of Skype,  done ostensibly to add video chat to Windows and match the success of  the iPhone’s FaceTime and Android’s Google Talk applications. Ballmer  mentioned Skype in passing toward the end of his keynote but did not  elaborate on the company’s plans for the technology.
 Regarding Microsoft’s departure  from CES, Consumer Electronics Association CEO Gary Shapiro said prior  to Ballmer’s keynote, “We agreed to a pause.” He added, while standing  onstage next to Ballmer, that he expects Microsoft will be back at CES  at some point. Ballmer neither disagreed nor said much else on the  matter.
