It's not unreasonable to think about 10, 20 or even 30 years with mostly incremental improvements and no ground-breaking changes in both smartphones and smartwatches. I list some examples below. Several of them are already under development, and some are already available but just not cheap yet. - Batteries that can be fully charged in 5 minutes; - Autonomy to go for a month without a charge, achieved by the combinations of new technologies in batteries, screens, chips and better software; - Scratch and shock resistant screens that can be equally visible on daylight and at night, maybe by working like and colored e-reader screen when there's enough ambient light available, thus making reading more comfortable; - Some kind of battery charging technology that improves over the awful usb connections that we have nowadays, whose cable connectors don't last much; - Better cameras that rival today's DSLR. There are some experiences going on using several small combined cheap sensors in a single smartphone to achieve results in the DSLR range; - Cheap and fast disk storage over say, 10 TB, as fast as RAM; - Cheap and fast data connection at any location of the planet. Like streaming HD netflix in your tent in the middle of a blizzard in Antartida; - High quality, small, wireless earphones whose batteries last for a week without recharging; - Simpler, faster and more efficient development plataforms; ... And I'm sure you can add a few more. Each of these are changes that separately would not be considered exactly ground-breaking, but all of them together could bring mobile computing to a whole new level.
