NT 4.0 (Score 1)

This may not be popular but I was never a fan of win95/98/me to many problems NT 4 was the biggest step windows ever made. I worked with it a bit today and after about sp3 their was really nothing wrong with it. I have many customers who have been using it for years and lots that really would have no benifit to upgrading. It really was the last really good change microsoft made and was a quantum leap over win9x.
