Now that I have an eInk reader with a decent size screen, I would love to read everything on it and get rid of all my books. Paper books are heavy, take up too much room, and use trees. Plus I hate the musty smell that books acquire after years in a humid environment. I haven't walked into a physical bookstore in years and when I buy paper books I always buy online.
About the only preference for physical books I have is for reference type books. *But* I haven't seen many technical books for eInk readers so I haven't tried one out on it. Trying to learn a new skill or acquire knowledge from reading a book on a Palm is too difficult for me. I have shelves full of needle art books that I'll have a hard time replacing with an electronic version unless I do it myself.
