I wonder if there's new feature or improvement Apple could introduce that would actually increase their sales. It seems like at the moment people buy the new iPhone because 1/ they need/want a new phone, 2/ they want an iPhone, and 3/ they want the new iPhone. Apple know what they need to do to be successful, and that's continue to release updates to the iPhone that in a few small ways make it slightly better than the previous one.
