Have Cell phones reached their limit

When I think back to when I was a young man I could only imagine being able to phone someone and seeing them on some kind of screen. I could only imagine what a digital camera would be like.

With the race to improve and advance technology on cell phones, one of the biggest money making businesses in the world today, where to from here ? It seems all but impossible that any further advancements are possible ! Perhaps better cameras, more security features, stronger touchscreens ? a few more apps and perhaps some added techno gadgets.

But in reality I cant imagine anything more that I would like my cell phone to do !
