Good deal. The only thing I worry about as far as personal docs (deDRMed Amazon books, etc.) is whether they will fully sync between the Mac OS X and iOS devices. As we know, Amazon takes away some syncing capability from "personal docs" so I wonder if Apple will do the same. Hopefully not. Another bad thing for the iPhone iBooks app is the lack of very small margins. This is true of the Kindle app on iPhones too. Margins are not a problem on large screened devices like iPads and computers, but they need to be tiny on small devices like iPhones. For some reason neither Amazon or Apple seem to get this.
