I say this only because I think when it comes to mobile phones we've hit the ceiling, how much more, other than a slightly bigger screen and better battery life, could the iPhone 4S hardware actually be improved upon? It's more down to software now more than anything... The next step would be eliminating the need for a chunky brick and replace it with something that handles the processing and some sort of display, be it projected or in glasses etc and the ability to talk to the devices and it executes your command and dictates flawlessly. This would open up a whole new world of possibilities to those with poor eyesight or people with limited accessibility etc. Thoughts?
