Sony on Wednesday announced its new VAIO X ultraportable laptop during the IFA 2009 expo in Berlin, Germany. The 11.2-inch ultrathin lappy bests Apple's MacBook Air in portability by measuring just 0.55-inches thick compared to the MacBook's 0.76-inch frame.

Official specs are still being finalized, though the one being shown off at the expo boasted an Intel Atom processor. Sony says its ultrathin will come with built-in 3G wireless and a new all-day battery that "will set the new standard for stamina," which supports the notion that the final version will come with an Atom chip inside.

Other details are few and far between. It has a carbon fiber chassis and weighs about 1.5 pounds, but other than that, there isn't much else to go on, including price and availability.
