Apple is certainly very good at their core business of building hardware and software, but the thing that sets them apart from the rest is their unimpeachable Brand Halo. Owning Apple products is now considered the ticket to entry for affluence. And 2 billion devices hasn't done very much to dilute that position. Android users (myself included) will show off all the incredible features you get on a device that costs half the price of iPhone and not make a dent in anyone's opinion.
