Apple is working on an iCommunicator, it will clip on your collar and allows you to make phone calls. It will be a shift in voice communication, using siri to voice control it.
The iPhone will lose its voice dialing functions transcending into a larger than iPhone device to carry along as your agenda, office, video conferencing , browsing device. The iphone screen is just too small and not very usefull. The device form factor will be extinct shortly.
And gaming will shift into occulus rift headset like devices. No one will play games on flat screens 10 years from now (unless you will be playing retro games)
It's time to rethink form factors and make specialist devices for specific functions. The generic pc and laptop form factors are dead, you only don't know it yet.
