Any new UI innovations that isn't already done in Android?
Are iOS and Android continuing to converging on the same features? What new innovations can be found in the mature mobile market or should be look to other form factors?
That said, I find nothing wrong with Apple adding features from Android (and vice versa) where it fits the device. The only thing I miss about the HTC One M8 I had was that I could double tap the screen to wake it (that rounded back loved sliding in the car. Reminded me of the iPhone 3G/3GS. Kind of disliked the phone outside of the double tap to wake and the speakers)
AR/VR is where the new innovations are happening. ARKit, Tango, Oculus, Hololens, etc.
Even this point is highly contentious.
AR/VR is interesting but won't take off until the hardware lowers in price..significantly.
