A) Apple is innovating the user experience. The author even specifically says that Apple is far ahead in the game, but doesn't seem to acknowledge that this is precisely because of past innovation. B) It's not even necessarily Apple who have to innovate. There are tons of developers writing libraries for iOS that make UX and user experiences better. Tons of developers meaning more developers than exist for Android. C) To claim that Android designers are innovating is just such a weak claim. Most Android apps I see are either ports of legit iPhone apps or really awful designs, note that I specifically mention the design.
