So seriously, can we get a feature matrix of what AppleWatch stuff you need the iPhone for? Jony sez in the video that you can "play music directly from the AppleWatch if you leave your iPhone at home when you go for a jog". But you need the iPhone for GPS, and most people like to track their runs/walks/cycles. Would be hilarious if the thing is pretty much useless in situations where you have to put your phone into airplane mode, for instance.
