Having recently installed Microsoft Vista in anger on one of my machines I have to say I am disapointed. There is not much in the way new (useful) features and the default security setting would drive you to drink.
Having defeated the security and installed my default suite of products I think I may have wasted my time and I may revert to WinXP. I have seen only one advantage, with Lightroom and thats because Vista allocates more memory per application so it no longer complains about lack of memory which it did under WinXP.
What a waste of my time......
