I did have the displeasure of using Windows Me at a job I had in 2000-01; it offered nothing substantial but did change some Excel commands. We demanded and got 98 back. Which only illustrates how worthless it was as an improvement (in a commercial environment, anyway). We asked for 2000 and were turned down flat.
2000 was an NT based version, and so was indeed much superior to any of the DOS based Windows.
