Interestingly, at about the same time as its release, BeOS machines with a very different low-level architecture could run 3 or 4 videos simultaneously. AND (the absolute jaw-dropper) you could grab one's title bar and shake it all over the screen without ANY of the videos so much as flickering.
It's only in the last few years that I've seen "modern" retail kit capable of doing the same.
