I did not even think of it that way, DUH on my part. You are right, they are not going to give up there format and open up another way for others to get books for there device. No library books are not that big of deal to me, it is just icing on the cake so to speak. It would be nice to be able to do that, but not necessary. I love my Kindle. They have screensaver and font hacks for the Kindle, so why not a book format hack? LOL
