Eh. Win 2000 was awesome compared to Win 98. Admittedly 98 was better than 95, and both ME and 8 sucked.
But by the time you got to about 2010-2015, then the optimal solution was to leave Windows and go to Linux.
I do know in the late 90's a lot of people were using Windows NT around campus ( I was in college) but I never really understood the differences. I vaguely understand that NT was supposed to be for networking and more corporate environments. I did use NT some in that time, but mostly at school. As I recall, it had a different file system, but I really don't know what the differences were.
Astonishingly, I've never used Linux, but I've always wanted to try.
