I think the future of smartphones are foldable either in the middle like a foldable sheet of paper or expandable flexible oled displays formed like Chinese hand fans or origami.

Further more the cell phone of the future will be able to borrow any big screen in its vicinity. Something like NFC from the large display/computer monitor and built in AppleTV, Google Chrome MiraCast functionality. You will also be able to borrow local keyboards for better input, but without the bluetooth hassles of setting it up. So the cafe, workplaces of the future will have wireless chargers and screens that you can borrow for your mobile device.

So you will carry your device around but borrow larger displays and keyboards. The device will be powerful enough todo your everyday computing. No need to drag a big laptop around if you do not want to.

These devices will also be user serviceable like Google/Motorola Project Ara. It is simply not good for the environment to throw away a whole phone just because the display, battery is bad or because you want to upgrade the radio components. So in the future devices will be made to be recyclable, this trend will be driven by the scarcity of rare earth metals. It will simply not be good enough to buy and throw devices and not think about the recycling of rare metals and the environment.

The future is bright.
