I have been using Vista on my game machine for a little over a year now... love it!! I havn't had one things go wrong with it. Most people who say they don't like Vista havn't even used it. Yes it takes up some RAM.... mine ~30% - 35% but I have 2GB.... RAM is cheap.... not hard to get more. Windows 7 is basicly a re-release of Vista so that all the Vista haters out there will shut up.
