I think ibooks and the kindle are great. The biggest plus for me is that I dont have to have a physical copy of a book taking up space. The drawbacks for me are: 1) I think the e-versions of books are crazy expensive. Charging the same price for an ebook that a physical book costs is highway robbery. 2) I generally only read a book once, there are exceptions, but these are few and far between. It seems to me that an online elibrary is the best of both worlds. Charge a fee to sign up, than charge one to bucks to rent or borrow a book.
