I don't know, part of the joy of reading a new book it's the feel of the cover, pages, etc.
All you people who talk about how great it is to feel the cover, pages, etc., you obviously have never had to tote around War and Peace or Gravity's Rainbow for a couple months on a train or bus. Sure, I love books and have nearly 2000 at home in my library. But I'd like an e-version of them too because sometimes it's an absolute pain in the ass to carry them around.
