It does. But not yours. 😀
At least that's how it would figure with me.
Depends on your book publisher. My school uses ebooks, but the company they use refuses to use anything other than native software. One of the reason I like the HP Slate is I can install their native software right on the slate and take my textbooks with me.
Plus, used books are a large source of revenue for campus book stores. I don't see them going without a fight.
