If they can undercut CourseSmart's prices, this would be huge. I just paid CourseSmart over $100 for a semester virtual rental of a textbook, and that's way too expensive for an eBook. I don't mind paying for quality content, and purchase apps and eBooks. But $100, and I don't even own the book, when the paper copy costs only 20% more and you could keep it forever or resell it? That doesn't make sense.
