I think the evolution or the future of smartphones will be difficult to believe, because of not just companies but and buyers will buy only "Flagship Smartphones" not any cheaper smartphone, that don't come with a lot of features on it or doesn't let you to update any more.
And for VR-s, I think that are good idea for realize imagination (like watching a movie with any 3D Glass to feel like you are right on the movie), but a lot of them are just expensive, and I think that "VR" means a way to get on movies,games,controlling an device without touching etc... But many of people are not interested on them while many many countries aren't on last technology inventions and are fighting with unemployment.
That's all ...
