given that w2k and xp are the same build, it's kind of aggravating that MS abandoned a perfectly good OS just to re-monetize.
I'm reluctant to upgrade to vista for my work machine because i work in cg animation and whenever vista hits a folder of images it tries to cache 4 different sizes of thumbnail of each image, which takes forever. when you work with 400 frame renders for a single scene, this caching is unacceptable.
My point was that the move to XP was an upgrade for all the 95/98 users, but for people with 2K all it did was rename a lot of the libraries and break functionality so that we would have to buy an OS that didn't offer a significant upgrade in performance or practical features.
