I can still remember a friend getting a HUGE mobile phone years ago and thinking it was great to be able to make a call from the car - but what was the point when there were pay phones everywhere? Fast forward to today, and we have the internet in our hands, and information any time we want. We can make calls world wide or get off a plane in another country, turn on our phones and call home. We can text people, we can follow directions so we're never lost, or we can read if we get bored. Way back when, did you ever imagine you'd be holding a supercomputer in your hands?
