You miss the point. The low end matters
. People who can only afford, or choose not to spend their resources on, the high end, end up being the majority of consumers over time. This happened in computers, and many gadgets (althought not in music players - so far). Eventually the high end becomes niche, and the low end rules. And if your niche is separated by technological barriers, it will never recover.
A buyer of a low-end Android phone may someday migrate up to a high-end Android phone, but they won't migrate over to a iPhone. Just like an iPhone user won't migrate over to an Android...
