why the hell would anyone want a tablet? i mean, it's probably too big for pockets (or if you squeeze it in, it'll be uncomfortable) and it'll be just like all the other crappy mini-laptops out there.
think of it this way, it'll be about the size of a portable dvd player. what's the point in that? if you need a PC that bad when you're on the go......get a full blown laptop (MBA or MB or MBP). If you don't need a PC that bad, but just wanna surf the net, watch movies, play games.....an iphone should suffice and it fits in your pocket.
this is a bad idea and the only market that exist for a tablet is for HARDCORE fanboys, not 99% of the other population.
this will be a huge dud. the only purpose the tablet will serve is to TEST technology so they can use it in future MacBooks and iMacs.....nothing more, nothing less.
