Toshiba's Excite tablet, or the AT200, received its US debut on Sunday as the Excite X10. The Android 3 tablet is due to arrive before the end of the month in 16GB and 32GB versions. Unusually, though, Toshiba is hoping to ask for a premium above an iPad, asking $530 for a 16GB version and matching Apple at $600 for the 32GB edition.
