I agree whole-heartedly with the dynamic icons. - Weather apps that display weather directly on the icon (I don't understand why Apple never did it for themselves). It would be trivial for iOS6 to implement a protocol where the OS could "poll" the app for a new icon only when the icon is visible, and only occasionally for performance.
