I had to pay a mandatory $80 e-book fee for every course while working on my master's. They are all gone now, of course. No way to recoup that cost by selling used textbooks when they have DRM. It's a scam to make $. I like when publishers put a deep discount on the e-book. But, long term, I think retail e-book sales will increase way beyond what we've ever seen with print books. I'm all over it now... Kindle Touch, Kindle for PC, Kindle for Android, Kindle for iPad, I love it. I'm going through Joe Haldeman, Anne McCaffrey, Greg Bear, and others. I read much faster on the kindle than with a paperback. something to do with the way you turn pages, it's a faster read for me personally.
