I wish amazon would bundle the ebook with the physical book for an extra dollar or something. I've often gone to buy a book, and thought maybe I'd buy the ebook so I could start reading it immediately on my iphone. But then it's not substantially cheaper than the physical book, and I decide I'd prefer the physical book.
