Vista, Just say NO
I was at the Dublin launch of Vista.
It was marvelous to see all the funky things you could do with it. It was blindingly fast on the laptop the presenter was using.
We then caught a glimps of the 4GB mem and out there graphics card. Serious bucks worth of hardware!!!
Needless to say that when I received my free copy of ultimate I threw it in the bottom drawer of my desk and it still resides there unopened and long may it live there.
