This is a tricky one. I’m looking for some technology from any time in the last 20 years or so with the following characteristics:
1. It is ubiqutous.
2. It was done right–ie, it’s a good thing they did it THAT way instead of some other way.
3. It is either true or believable that it COULD have been done some other way that wouldn’t be as good.
For example, the 26-key pad on the I-phone makes life better than if everyone had to triple-tap. Unfortunately, that fails #3.
Any and all suggestions welcome. Thanks!
