I ran across this article link on ConversationalReading.com today. This guy who describes his relationship with books as "just this side of pervy" agrees to read e-books on a mobile device in lieu of paper books. He writes about the experience.
I don't think I'd ever embrace e-books--I appreciate the paper too much. Audiobooks I can do, but if I'm going to be reading a book, I want to read a book.
