One of the first low-cost Android tablets with an Intel x86 processor was announced at Mobile World Congress, setting the stage for a long battle between the world's largest chip maker and ARM, whose processors go into most tablets today. Asustek released a 7-inch tablet running a single-core Intel Atom Z2420 processor code-named Lexington, which is targeted at low-cost smartphones and tablets. Priced at $249, the tablet has 3G voice and data capabilities, and Asus claims it offers nine hours of battery life. The tablet includes multiple cameras and a 1280 x 800 pixel screen.
