And in terms of iPhones / Population / Apple Store, the US has it most. While in Japan 60% of the Smartphone are iPhone ( i.e Higher the US usage ) they have less then 10 Apple Stores. And it is the same everywhere else, which means any mark up in a certain countries has nothing to do with its Operation with in, and more to do with a Sales Tax, Global Pricing structure.
For Example, HongKong used to have the cheapest iPhone around the world, it was priced the same as US and because there are no Sales tax, it was 10-15% cheaper. Making HK the trading ground for all of SEA region or mainly China. ( Hence Tim Cook continue to blame HK market is more of a delusion rather then fact. ) Around iPhone 5 Apple started to put up additional $100 USD to ALL iPhone price in HK, as a way to combat the black market trading, and if everyone else where making money of it, why not keep the profits itself?
What has all these got to do with $1K iPhone. Well Apple already knew certain people are buying at those prices, again why not make a product that fit those segment? And to re balance the prices across the Globe?
And we have known for long there is no way to make the cutting edge devices every 12 months and ship 200M+ of it. They will need a product that only 10-20% of those 200M will buy, and have the best technology in it.
And mind you, shipping cutting edge technology to 20-40M user a year isn't any easier then the 200M+ iPhone.
