On a slightly serious note, if they manage to bring it out in a size that could be used on a table or desk (of course, highly scratch ..etc. resistant), I might even consider getting something like that.
Imagine having a table that you can use for board games, throw up some news, tv (hopefully iTable supports Flash). Of course it would have to allow several windows which each user may orient to their liking.
The Microsoft D&D table demo looked quite nice, but I dislike the idea of having a seperate computer around to feed information to that thing.
