We had a long, hard look at Vista and decided against it (rather like the Chinese for the forthcoming Olympics). The exam question we asked ourselves was "what does Vista do, that we need to do - that XP doesn't?". The answer was nothing. We will take another look when it is a little more mature, probably a few months after release of SP1. Why invest in a new OS when the current one meets the requirement? If it ain't broke - why fix it?
