IBM's ThinkPad Tablet PC

We just got a tip that IBM's first Tablet PC has been spotted in the wild. We have one of our best big game hunters hot on the trail for some pics (if you've got some, send 'em in), but in the meantime we do know that it'll basically be a convertible-style of the ThinkPad X40 (pictured at right), which means it'll probably look just like a regular non-Tablet X40 just with a screen that swivels around and folds down so you can write on it. Oh, and that it might be called the X50.
