conspicuous consumption. People keep buying iPhones to show off they can afford it. Even when the top of the line samsung phones cost more and are better most don't want to be caught dead with a android phone.I think it’s a reasonable expectation for an iPhone to last for more than a year and a half, otherwise they would not sell much if at all. If it did indeed fail without user error, then it is not good quality. You will see an iPhone 6s in the wild and you’ll see a 2006 Toyota - the warranty was over a long time ago.
