I like they are trying to shake things up here. I don't buy books anymore because it's no longer useful to have a shelf dedicated to books I will never read again but I appreciate that there a ton of people who are weary about the digital medium who may need coaxing - this is a perfect segue into the Kindle for Amazon. Huge step towards adoption once they get more publishers on board.

As a side note I love how 80% of the comments here are about the number of books available as a pissing contest versus any real discussion for the merits of the idea. For shame.
