I don't think there is anything in that video that is not achievable with technology today, but two OLED screens that size would not be inexpensive right now...I've seen other working demos of that type of page flip though, and some nice dual screen interactions as well.
I love demos like this-I think a lot of people have vague ideas about what they want and don't want in an e-Reader, but seeing stuff in action is the best way-even if it is a canned demo
