Neonsamurai is right. XP original was the same. Vista is no different. Both have good sides and bad. I've got windows 7 evaluation copy on another partition. I find I get more performance from win7 than vista. There are many feature similar to vista on windows 7 but less nonsense too.
Anyhow I'm sure there will be people complaining about win 7 like very new OS there alway issues.
I sure do miss the dos days... You can never go wrong there..
