I'm about 75% ebooks now. I still read real books, but I like to have at least one ebook going at any given time, so that I can whip out my phone and read if I'm standing in line somewhere, or the like. Plus my basement is almost at saturation for bookshelves. (I actually hauled several tons to the dump - couldn't give them away. (Not really true - hired some kids to do it, since I couldn't do it myself.))
Also amazon has this fiendish deal going when you discover a new author... the first ebook is $4, but then if you like it, the next ones are $10. In the last 24 hrs, I discovered Scott Shermann's " Kevin Connor Mysteries, and burned through all three of them. Almost as god as sex.
