BeOS was by far my favourite operating system of that era. Fantastic platform that really put the competition to shame. Fast, stable, pretty and powerful.
Same here. I still remember when I first booted it up and ran a demo app (video playing on all sides of a rotating cube), how much it put OS 9 to shame in terms of responsiveness and performance. I’m still pissed that Apple went with NeXTSTEP instead of BeOS for OS X, but I’m glad they went with something.
