Engadget asks how would you change Apple's iPhone 4S? Personally I wouldnt change anything, I'm very happy with it. "In the cold light of January, we can see the 4S for what it is: a refined experience that lacks a compelling reason to pay an early-upgrade fee. If you were in the planning meeting for the iPhone 6 (it's a hunch), what would you be pushing for? Built-in NFC? Would you have kept Siri under wraps until it had left beta?"
