Toshiba's new Excite X10, on display at the company's private event at CES, is being billed as the world's thinnest and lightest 10.1-inch tablet at just 1.18 pounds, and 0.3-inches thin. Toshiba last showed off this tablet in Tokyo last fall, at the CEATEC trade show; there, it was called the Regza. For its U.S. debut, the physical characteristics remain the same, at least, including its Texas Instruments 1.2-GHz OMAP 4430 multicore processor, 1GB of memory, and 1280 by 800 resolution IPS display. The display looked good, with a minimal air-gap and a wide viewing angle; but text and graphics weren't as sharp as on the Acer Iconia Tab A700, which has higher resolution. Battery performance is not final, but Toshiba says it expects 8 hours of continual video playback. Let's take a closer look.
