@Gammitin in fact qnx/2 is what kept me away from windows. I had a multi-port (8 port) serial board that worked with qnx, and used multiple terminals for running multiplayer terminal games off it. I tried OS/2 as well, but Windows seemed like complete junk as a software architecture even back then, so I refused to touch it. Then I tried this new thing called Linux, and never looked back at where the rest of the PC industry went...
