I'll chime in as another oldie that started with Dos and Windows 3.1. Also ran 95, 98, and NT4. Skipped ME but loved Windows 2000. So much so that I really resisted switching to XP. Once I did though I ran that for a dogs age too. Then just skipped Vista and went to Windows 7. Its on all my rigs now. I have to say that running it for the first time gave me one of the biggest "wow" moments I can remember. I'm definitely not feeling that with Windows 8. Its more of a WTF moment with windows 8. Windows 7 runs great on all my rigs and even lets me play my old games on the 64 bit edition.
