I upgraded to this at the weekend. I really like it. Much better than xp in my opinion. Faster & more slick. The gadgets and widgets are a cool utility too.
Also, the voice recognition is a laugh. I was just sitting there shouting commands to my laptop. I managed a post on mansized and I never touched the keyboard once! How cool is that.
I also managed to use a program called TVersity that streamed music and vids from my laptop to my xbox360 which is cool as well.

I'd recommend peeps to upgrade and say 'astala-vista baby' to XP!
