At a press event in Los Angeles today, Microsoft today unveiled Surface, a line of tablet devices running the company's next-generation Windows operating system. The tablet wars are no longer a two-horse race between Apple and Google.
 The Surface tablets will be available in two distinct versions. The Windows RT version -- which is effectively the "light" version of Windows 8 -- will launch with Windows 8 in the fall, and run on an ARM CPU. While it won't have the full desktop version of Windows 8 (it runs only the "Metro" apps available through the Windows app store), it will include a version of Microsoft Office at no additional charge. The distinctive feature of the new tablets is a magnetically-attached, 3mm-thich Touch Cover that folds down and functions as a full touchscreen keyboard. The Surface tablets feature 10.6-inch touch-screens wrapped in a magnesium case that Microsoft calls VaporMg (pronounced "Vapor mag"). Another cover option, the 5-mm thick Type Cover, has a built-in track pad. The keyboards power down when they're folded back against the tablet thanks to a built-in accelerometer.
