> Many people nowadays don't have a computer especially in that big Asia demographic that Apple so loves.

Many people use battery packs, in fact, on a recent trip to Tokyo, I bet almost everyone had a battery pack - it was commonplace to see a little USB wire coming out of the bag and into the phone. And also, many of them used headphones - that would turn out bad when competing for the same power - and strangely, almost everyone had an iPhone 6, so, I don't see how they will manage with the 7. There are so many iPhones in Tokyo that it feels like the Nokia of the 2000's.
