It wasn't as big of an issue. And there's a limit on how small you can go, especially with batteries. It's not "just a matter of time".

  > It wasn't as big of an issue Clearly you weren't around when cellphones came out. They were seen as borderline miraculous devices, even if they were huge. The first phone weighted 4 and a half pounds! Even at that size, people didn't believe it was possible. Remember, that pre-dates personal computers. No laptops existed. It was a big deal and required newer technology and even advances in mathematics (for the cellphone signal processing). We can make them tiny now. So tiny, in fact, that you can have tiny spy devices which are nonetheless able to talk to cell towers. Sure, we can only make battery so small until they can't store much in terms of useful energy. But that also depends on how much power the devices require. An Apple Watch was an impossibility until not too long ago. Not just because of battery size, but also because of power draw (specially from screens). Have you seen how small an Apple Watch battery is? And that powers quite a bit of compute (an Apple Watch equals to about 2 Cray supercomputers from 1985, around 3 GigaFLOPS). It is a matter of time.
