Care to elaborate why iPhone is far superior to Android, because simply i failed to see that is the case. I have both iPhone and Android phone (Huawei, Xiaomi, Motorola, Smartisan, Google Nexus etc), I can seems see the advantage of iPhone, rather than the high price tag. There are so many more people using Android and the number is growing everyday.
Yes, Apple owns the high end market. High end market is also the dying market. As mid-range phones becoming more reliable and speedy, more and more people will opt for mid-range phones more than people opt for high end phone. You see this with PC market, high end PC only make tiny share of PC market share while overall PC market are in mid-range PCs.
This would occur with smartphone market as well. As iPhone becomes more and more expensive, lesser and lesser people will opt for iPhone.
