Perhaps, but I didn't realize it was poorly executed at the time. :-)

I sure put mine to use. It was essential in my grad school physics research in the lab. Later when I became a high school teacher, I was the only one at the school with a graphing calculator for a while. It had quite the WOW factor. I used it till in died in ~2004.
