Let's consider strategy. There are two variables: P, the price, and Q, the quantity. Of course by reducing P you increase Q, and vice versa, so besides being dependent on each other, they have an inverse relationship. At some pair, PQ is maximized.
Apple knows this. So of course they did not set the price P to maximize Q. They set the price P to maximize PQ.
The question should be why P maximizes PQ. I submit that it is because of dopey articles that create a luxury effect around the product. I believe that if necessary, Apple would (and may even already) write and publish these articles themselves.
