i started using linux in the mid-90s, after using commercial unices for the previous 10 years. i was amazed at how well-engineered it all was. i think i was using slack - too long ago to remember.
The only guy I knew who used commercial unixes at home back then, lived in Seattle and loved to play games.
Even got his girlfriend interested in them, which was unusual at the time.
Come to think of it, I remember one day some government goons took him away, right around that big nuclear scare. And no one has heard from him ever since.
thanks linus.
