I don't consider the iPhone a phone, I consider it a small tablet. In fact, from day one, I was wondering why Apple was calling it a phone, when phoning is clearly less than 15% of its capabilities even back then.
I guess it has to do with the popularity of telephoning, I never got that, I barely use it. But the general population surely do. In my town, the center does not have a single vidoe store, but it has six mobile phone stores next to each other!!
So anyway: for years I've been wondering: what did we do before the Internet?
Now I'm already starting to wonder: what did we do before tablets?
Example: I was talking to somebody about the speed of electric kettles.
I thought: I'll bet anything there are several stop-watch applications for the iPhone. And what do you know, so there was. There was even a free one, which is excellent and very aesthetic.
So I could measure with ease how long it takes my electric kettle to boil two mugs of water. (1.42m.)
Obviously, the point is the bigger picture: this sort of thing will happen again and again and again, in so many areas we can't even imagine them.
(An example is an App which a friend showed me: if he hears a song, he holds his iPhone up and let it listen to it for a few seconds... and the app tells him which song it is, and where to get it!)
