Google Books not compatible with Kindle. I have had old Sony Reader, Kindle2, and iPad. iPad is the winner because it does so much AND is a reader. Plus I love that with google books I can buy books from independents, barnes and noble, google direct, free books from the library, etc. Once you go Kindle you are forced to buy all your books from one place: Amazon. Just my 2 cents. I still like real books at least half the time - they are like old friends throughout my bookshelves in my home.
