I used to run BeOS on a Umax c600x280 Mac clone (PowerMax, Umax, Motorola days). I loved it because the UI was responsive. There was no lag. It also introduced me to the command line.
The previous year, I tried an mklinux install. I couldn't tell upside from down. I didn't know enough to "man" a command, let alone which commands to man.
I'm sad Be never became OS X. I wonder what Haiku/Be would be today. Remember the first OS X version? It was slow and buggy. 10.1 was usable.
Maybe Apple would've made a slow, buggy OS B. Back then, it was on.
