I think it's closer to the mouse. When I was in seventh grade our computer room had an Apple II and a TRS-80. Apple had made floppy drives standard. The try-80 had a tape recorder and magic incantation for storing and retrieving programs.

One day reading the latest computer magazines was Steve Jobs talking about a computer so easy to use a 2 year old could use it. I could not begin to comprehend what he was talking about. He was talking about the Lisa. I don't know how long it took me to find out what in the world was going on.

It maybe like 2 mouses in that it has eye tracking and hand tracking. Which might make 2x as good as a mouse.
