Where would we now be if NeXTSTEP had taken hold?
Watching Steve's demo of NeXTSTEP above really makes you realize how ridiculously ahead of its time it was. It was literally lightyears past anything else available at that point (late 80's, early 90's).
Which leads me to the main question of the thread: where would desktop computing be now if NeXTSTEP had devoured the market back then? I can't help but think it'd be in a considerably more advanced state. Furthermore, the broadband revolution, cloud craze, etc probably would have come much earlier.
