Hello everyone, I am brand new to this site and to iphones. I just ordered an iphone 5s 64GB from an individual for $550 shipped. It should arrive next week. It is factory unlocked, and I plan to use it on Cricket Wireless. I realise version 6 will soon be available, but I concluded that it will likely cost $800 or more for iphone 6 with 64GB's worth of storage, so I opted for a brand new 5s for a much lower price. It makes good economic sense to me. My question is why would anyone who purchased a 5s at the time it first came out now want to spend close to $1K for iphone 6 just a year later just to have the newest model? How do you justify it?
