Incidentally, my take on the article and the survey it's based on - utter rubbish. Firstly, why would members of the public have any insight into what's coming, and especially the time frame? Second, five years is nothing. Even in tech - we've had smartphones far longer than that already. What they can do has improved, but they're still fundamentally the same thing, just a lot faster and more powerful. The next stage of mobile communications I'd wager will come a long way after 2020.
Also, people talk about voice control etc. But there are lots of situations where it's impractical to make searches or receive info in voice form - in noisy environments, in crowded places with lots of other people, etc. A screen allows me to silently interact with my device, and nobody can intercept it unless they get really close and are nosy. Until and unless there's thought control (a long way off, see above), screens will be essential.
