Apple has released an official video showing what books will look like on its new iPad (which I'm still not sold on, but interested.) I'm generally bored by videos like this, but this is really cool.
Heck, I think it would be even better for magazines and textbooks.
And if you are Barnes and Nobles, aren't you just a little bit nervous?
Edit: A collection of a variety of official videos for the iPad which have just been released is on this site.
