I took Computer Art & Animation in 1990. We used programs that most of us will not buy ourselves in our own lifetime (Ever hear of Tips, Topaz and Rio?!) One of those packages cost $20,000 at the time, and it was the one we used the most. At any rate we had graphics tablets then, with "pucks". (That's what I call the cursor which is like a mouse. We got to try the pens for a time. I didn't like it because I had to keep picking it up and putting it down. Too much hassle for me. I stuck with the "puck." That's why I have the 4-button cursor with my SummaGraphics tablet.
