What Kind of New Technology will be the NEXT???

what new technology will be next?

I was thinking now what would be next technology with mobile devices... Well, smart watches are coming up from a lot of companies... Well, how about anything new? 
Huh, I don't know what to think yet, but I know that people are little bit getting tired of all smartphones. It is a good thing that new thing comes up now than in the future. However, it is hard to image a new mobile device since we have smart watch, mobile phone, cellphone, smartphone, Tablet devices, LapTops and Computers.
However, one thing we don't have yet for our life, that is less battery required devices. It is hard to maintain for all devices without battery right now. But our battery is short of time use for most of them (unless you don't use it for more than 1~2 hours a day). Well, maybe next few years people will develop to have less battery required devices... or no battery needs. I know several cellphone had solar powered charging system, but that take more time than just changing from plug. Well, maybe soon, we will have better technology for solar power charging system. Well, I like to use my cellphone anytime, but still short battery life... So sometime I need to have charger with me... 

What would you think our next technology be?
