Does anybody have any experience using or, preferably, buying graphics tablets? I'm looking to buy one for my girlfriend for Christmas and I really have no idea what the hell I'm looking for. She wants something that she can carry around and paint/draw/etc with, so size and surface area are pretty important, and she has a pretty powerful phone so there is really no need for app or game capability. I'm looking for something fairly inexpensive, as tablets go, but anything under 200 is definitely under consideration. Ideally, there would be a durf/poing/boobies option for buying tablets.
