It's so tempting. That thing is GORGEOUS. I would have pulled the trigger if they had put 4x4 MIMO as part of Qualcomm Gigabit LTE and B14 in it, but they didn't do either, so I'm waiting.
I really hope the next iPhones still have unlocked Qualcomm models, if they go all-Intel, then I'll be forced to stay on Android. After having a phone with Qualcomm X12, the minimum I'd settle for now is Qualcomm X16 or X20.
