But the very first line of the article says, "Apple® today announced a new subscription service available to all publishers of content-based apps on the App Store℠, including magazines, newspapers, video, music, etc."
On the surface, this does not appear to include content providers like Amazon... at this time. We already know about the relationship (or lack thereof) between Apple and Sony and Amazon is not safe by any means. As we all know what happened with the screen rotation lock button, Apple can change the rules in the middle of the game!
As I have said before, I could really care less about the features of the 2nd generation iPad since my main reason for owning one was to read stuff. Yeah, I do love my gadgets, but the decision to upgrade depends wholly on what becomes of Apple's relationship with Amazon.
