I really like NT 4.0 as well. In my experience the stability varied based on hardware and driver support, though. I tried running NT 4.0 on a "relatively fast" K6-3+ system with GeForce 2 and AWE64 but had weird issues, like sound stuttering in games that the same hardware runs fine under Win98 and 2K. I had endless trouble getting it installed too, I ended up installing in 86Box then imaging onto the host. I could fairly easily get it to BSOD by doing multimedia type work on it. Really though, not a fault of NT 4.0 so much as I probably didn't have the ideal drivers or hardware combo. But on a fast 486 system, a bit older than NT 4.0 was really designed for, it ran flawlessly and made the dusty hardware feel very competent and modern - lots of common software runs fine on NT 4.0 including Winamp and specially compiled versions of modern PuTTY. It's probably my favorite OS for a DX4-100.
