Bottom line is that these new phones are needed by almost no one today. They're all "wants," and for reasons that grow thinner and thinner with each iPhone iteration. "Gotta have AOD!" "Oh, that new color!" "The island is the bomb!" But then you realize, fairly quickly, that you're just using an expensive new toy to do the very same things you did yesterday on your perfectly good previous phone.
It's all a bit sad, really, this vapid consumerism.
Sad buying something that someone wants? We all like buying things that we think are cool and make us happy. I wouldn’t pay £1500 for a phone personally but don’t care if others do. I certainly don’t take offence to it like you appear to do.
