Hey Guys !! I am a newbie in this forum. We have recently got shifted to new office and now looking for a good operating system for the computers. I have few options in mind, but I am confused should I go for Windows Vista or XP. Also I found a good deal for Windows Vista ultimate at eCostSoftware for £200. Please suggest should I go for it? Valuable suggestions would be highly appreciated. Thanks in advance.
