The only books I buy are books that I will use over and over again. (how to books, pattern books etc.) I read fiction once and I'm done. The kindle is wonderful if you always like to have a book with you. It fits in your purse. I order free books and delete them when I'm done. If you think you want to re-read a book just don't delete it. I'm not sure how many books you can download but I think it's in the 1000's.
