Windows NT 4.x improved performance at the cost of stability by moving drivers - which in earlier versions ran in user space - back into kernel space. I ran NT4 for a number of years, and it remains by far my favorite windows version. Maybe it wasn't stable enough to run a server (although I've heard otherwise, with uptimes measured in years), but I have no recollection of it crashing. It was essentially a modern OS that could happily run in 32 MB of RAM, which isn't even enough these days to launch a single windows program. My favorite desktop OS overall is BeOS R5. It was just so much fun to use. Not actually very useful, with the lack of apps, but definitely fun.
