I've seen young children hug and kiss them! I particularly liked the graphing calculator and have used it to teach trigonometry.
I had two of these running in a kindergarten class as late as a year ago.There are still great games available in OS 9. The faster of these are easily identified by the two FireWire 400 ports on the I/O side.
I think Cunnia's avatar would be the ideal computer to run OS 9.2.X (.2 was the latest ). Sorry Cunnia, but I can't help jumping in here.
