Actually, one thing that's bugging me is some kinks in the new iPhone update. My phone keeps randomly freezing and I have to hard reset it.
But I agree with what some mentioned, that with every new feature it just seems like there's less innovation possible next time around. Apple has the technology to do more (I assume for no reason,) but they don't want each gen to be a revolution, especially because they also (I assume) have to spend crazy r&d for such revolutionary model, as opposed to merely tweaking existing platforms. They want to push the envelope, but only slightly further than competition, not necessarily to their own limits.
