i don't think we're even talking about the same thing. 2000 is just xp without the jolly rancher start button.
Not really.
2000 was the culmination of the previous Windows NT family effort, with an administration and enterprise focus.
It was also around for a little while prior to taking the NT kernel and throwing it into a consumer OS. At that time, they had also improved the kernel and I do believe released updates for 2000 that were basically born from improving the kernel and OS for consumers.
I never interacted with 2000 prior to XP's availability, so I don't know what it was like.
I understand why people hated Vista at first, but I jumped the XP ship immediately and, while I had some issues, it was overall a vastly superior product. I couldn't stand XP.
Drivers, especially from Creative, sucked hard at the start of Vista, and it caused a major shakeup for drivers in general with the new kernel stack (that have produced lasting changes through today's 8.1)...
XP was basically the consumer-friendly version of 2000/NT5.0. Vista was the proper sequel. 7 and 8 are actually on the same major kernel revision, and while they have continued to produce sometimes significant performance improvements, no OS was as a significant jump ahead as Vista. That said, Microsoft helped clean it up and 7 was Vista on steroids, and more importantly, hardware providers got their drivers in order and overall helped make everything as stable as it should be.
Once a few problem drivers were taken care of, I found Vista to be amazing and vastly superior and FAR more stable than XP ever was. Which was interesting, because 7 was just as significant a leap in terms of both performance and stability.
