Perhaps I am just overly cynical, but I have been trying to figure this change to a taller screen out. I have seen these resolution changes before being the owner of a 2G iPod Touch, a 1G iPad and a 4S. Every time there is some new super resolution that comes out, the app developers end up soaking the end user for a new version of the app. In some cases the nicer devs actually release a universal version, but in many cases they do not. So, now get ready to repurchase all of your apps in the "XD" version or whatever they choose to call it. It is a win-win-lose scenario. Win for the devs, win for Apple and lose for the consumer.
