The first optical mice absolutely sucked compared to trackballs.

Fortunately, that period did not last long.

    First optical mouse I used was interning at a university engineering department in 1993. It had a special metal mousepad with a grid on it, and it worked pretty well as I recall.

    TIL it was a Kirsch design, one of the first, from 1980.
