A quick history lesson, since we're here.
The mouse was invented in 1964, and took twenty years to reach an ordinary desk. It didn't just add a way to point. It changed what an interface was.
Before it, you had to remember the command. After it, you only had to recognize it.
You could pick up a file and drop it in a folder. Computers opened up to people who were never going to learn a command line. And we learned its little language, double-click, drag, right-click, so well we forgot we ever did.
Recognizing is easier on the first day. Remembering is faster on the hundredth.
