To familiarize yourself with the rumors so far, not including this one, head to our giant rumor page.
According to the WSJ, the tablet will be pretty much what we expected: movies, TV shows, games, browsing, books, textbooks and newspapers. WSJ also mentions two different material finishes for the tablet, and if we know Apple, they'll only have one; the two are just final prototypes so that Jobs can decide which one he likes more.
So it's good to hear that at least some of the rumored features might be delivered, but that $1000 price seems a bit high. Not high as in we think it's wrong, high as in cost-prohibitive-MacBook-Air-style high. [WSJ]
