Ah, you know, it's rather Apple that should rethink its strategy. When you only sell so-called high-end products, there are 7+ billion people on the planet that will never ever be able to afford your products. So Apple is milking the people who have the money to spare, but there is a natural limit to that sales strategy as well. Unless everything capitalists want to believe and unlike everything they teach people in business schools, you just cannot grow forever. Resources - and markets - are limited.
Being able to reach a billion+ active devices with super expensive products is quite an achievement, and obviously a relevant market share in first world countries. But... "The rest of us" is buying something else that doesn't run iOS, and we are the larger community. Maybe not by budget, but by sheer amount of people. Even though people like to look at a Porsche and even though Porsche gets a lot of press coverage, most people on this planet will never ever buy or drive one, and most of what you see on the streets are cheaper low-end cars. But unlike an iPhone, a Porsche at least still is a real status symbol...
In the grand scheme of things, though, none of this really matters. These things are just cars and phones and civilization won't crumble if they go away over night.
