"Yes Windows 2000 was indeed good.. but it was good for it's time.. now is a different time and Windows 7 is taking that spotlight for it's time in my opinion.. " Windows 7 may become as "smooth" and as stable as Windows 2000 by the time it is 2 or 3 years old. But, 7 is not without a significant learning curve that is just not natural. I was a truck driver for a few years and drove several different brands and models of trucks. Of these trucks, only one just seemed to have everything right. When you put your left foot where you thought the clutch pedal should be, your foot was on the clutch pedal. When you reached where you thought the light switch should be, your hand was on the light switch; and it flipped the direction that felt natural to turn the lights on; etc., etc. MS operating systems moved little by little toward getting things "all in the right places" through 2000, then began moving to "creative stuff" that actually ran counter to intuition from XP on through and still including Windows 7.
Vista Windows Explorer, for instance, was and still is nothing better than a major disaster in which the typical, non-professional home user cannot find their files that they want to access. Windows 7, rather than fixing the nightmare added libraries which does, with some studying and practice, allow one to find most of their lost files but does not reorganize the file system to something logical.
It is true that "times change" but change for the sake of change that takes away from the serviceability of a product is not progress. While Windows 7 is a giant step forward from Vista, it still lacks a lot of the user friendly, intuitive features that Windows 2000 offered. The addition of libraries which indexes files that should be indexed logically to start with, eliminating the need for libraries, is an example of "better, but still terribly wrong".
Having said all the above, I do realize that it is not practical to try to use Windows 2000 as a "main" OS because as the world moves along, software needs change and 2000 does not keep up with these new software needs. But a lot of the features of current OSs are simply counter to productivity and counter to intuitiveness.
And that's my story, and I'm stickin' to it.
