Ha, I can't believe I got down-voted for this. To spend $600 on a phone, there has to be some emotional attachment to it given that you can get a really high quality phone for under $400 now (Nexus 5, OnePlus, Motorola X and G). In the US, the only company that holds that sort of attachment is Apple (and maybe Samsung). But, as T-Mobile and others shift to a more European model for phone pricing, I think we are going to see value phones in the $200 - $300 price point be dominant. That is not to say that there won't be a premium market, but it will be smaller. This is how mature markets work.
