hah! i forgot all about quake c.
in 1997 i had a windows nt 4.0 machine (might have been a beta) on my desk and a next turbo mono slab. visual studio wasn't terrible for development (and was a great place to get good at c++ and multithreaded), and they managed to bring all the directx stuff over. it was like windows 95, but serious and stable.
it replaced a slackware machine and a sgi indy. the indy was cool because it played a little song when you started it up and it had a novel ui with lots of cool color gradients, but otherwise it was kinda buggy. (the "objectserver" would frequently crash inexplicably. what objects did it serve? i have no idea.)
