^this, plus being able to play 3-4 quicktime videos at the same time smoked everyones brains around me. Using mac os 8/9 was a several times a day cursor freezing up and having to reboot. win95 was even worse
I think I'm remembering this correctly - couldn't you move the window while the video inside continued to play?
The one that blew my mind was you can drop a QuickTime movie onto each side of a 3d cube and they all played without dropping frames.
