Idiot. Hand gestures will never work as well or as accurately as direct contact with the screen. For occasional use hand gestures will be admittedly nice, but they will never even be close to the primary interaction method with the phone.
Reminds me of old American 8 Cylinder Cars,... needed 8 cylinders (and so worse MPG) to have as much horsepower as more advanced German BMWs and Mercedes got out of 6 cylinders. Fact is the Apple phones still work better, don't need as many "cores" because Apple Software (and only they have it) is vastly superior to clone Android software. The Korean Clone Phones have always had to use more megahertz processors, because their system-software doesn't work as well.
