It was the beginning of a new era at CES on Monday when Sony announced its first smartphone since the firm bought out Ericsson from their joint mobile phone venture.

Available globally in the first quarter 2012, the Xperia S is the first of the under fire Japanese electronics giant's new NXT series with the consumer heavy-focus as ever on multimedia and entertainment functionality.

Under the covers the device is powered by a 1.5Ghz dual-core processor and runs Android 2.3 (Gingerbread) although it will be updated to Ice Cream Sandwich by the second quarter.

The NFC-enabled phone has a high res HD screen, 12 megapixel camera and a new design dubbed "Iconic Identity" which Sony says helps emphasise the display.

Other nifty additions enabled by its Android OS include SmartWatch, which allows Android to wirelessly access calls, messages and apps and Xperia Smart Tags, which launch pre-configured, personalised settings when NFC Android phones are swiped against them.

Sony also pushed the device's entertainment credentials, saying it is PlayStation certified and offers access to the firm's Entertainment Network via an HDMI TV connection. Photos can also be shared wirelessly, Sony added.

Whether this device is the one to propel Sony into the top tier of Android smartphone vendors along with HTC and Samsung remains to be seen. Only time will tell whether its €1.05bn buy out of Ericsson was a stroke of genius or the final nail in the coffin of its smartphone ambitions.

Also at CES, Sony showed off its dual-screen Tablet P as well as the Vita portable gaming device and other innovations.

LAS VEGAS: Those of you who were hoping that Microsoft would leave CES with one last spectacular fizzle are in for bad news.

Steve Ballmer's 2012 keynote has come and gone without any power outages, system crashes or video delays. Despite an over-capacity crowd at CES, Microsoft was able to showcase its latest and greatest products with very little in the way of negative attention.

The final Microsoft keynote for the forseeable future highlighted many of the company's flagship brands, including the growing Windows Phone platform, XBox and its Kinnect platform, and the upcoming Windows 8 OS for both desktop and tablet systems.

Ballmer, aided by co-host Ryan Seacrest, was his usual dynamic self to the very end. When asked what was next, he emphatically declared "Metro, Metro Metro!" in reference to the highly-touted Windows 8 interface.

"Together, all of us in this industry, in thousands of new ways, will use the software and services and devices to invent incredible things," he said.

"Metro will drive the new magic across all user experiences."

And with that, Microsoft ends its days of headlining CES. Those of you feeling nostalgic about the whole thing will always have the memories of the company's historic keynote fails to keep you company.
