The way I read this article, It is less about building new smartphone but more about the next technology shift that is going to change the direction. Basically, as oft repeated Ford statement goes, 'if you asked people what they wanted, they would have said faster horse'. So, at this point, smartphone business is settling into a faster horse business.

So, I would really expect the next big thing to be not a be an iPhone but something utterly different. Neural implants, anyone?
