MSN admitted about Vista failure and also pushed Windows 7 yet again 2010, I think it is better to continue with XP since they're now going to support XP through 2014. Nothing bad! http://informationweek.com/news/windows/operatingsystems/showArticle.jhtml?articleID=208800494
well windows se7en will be completely different from vista. infact windows se7en will be based on multitouch GUI same as i phone's GUI.
Windows XP is good. lots of people like it better because windows vista crash's a lot on some laptops and gets the bluescreen of death.I would use XP until windows 7.
