9.7-inch (diagonal) LED-backlit glossy widescreen Multi-Touch display with IPS technology
1024-by-768-pixel resolution at 132 pixels per inch (ppi)
Both of these specs are disappointing. Screen size should have been at least 3-4 inches larger, and resolution 720p. I mean, what the hell is the point of advertising that you can watch "HD movies", if the screen will not even allow the lowest HD resolution? Or is 480p supposed to be HD?
Other than that it sounds awesome, especially the whole "book reading" + "bookstore" deal:
Reading is a joy on iPad. Text looks crisp and bright. Pages turn with a flick. And you can buy new books from the iBookstore. Just download the free iBooks app to get started.

As for gaming, it's just another handheld device, which means it'll have just handheld games, i.e. mini-games. That's another reason I would have preferred say a 14" screen with 720p resolution. So that developers might take it seriously and develop some serious games for it.
But yeah. That's what the Surface will be for I guess, or whatever other device ends up fulfilling its promise one day.
