I am a Luddite with computers.
I wanted a new laptop and desktop but was not prepared to buy one with Vista, so I hung on to my XP machines. The laptop was recently upgraded to W7, it's not an easy upgrade but I was determined to avoid Vista. I had it done by a pro and it went fine, unfortunately I have to keep it as dual boot as I have one application which will only run on XP, but when I switch between XP and W7 on the same machine, I can see how much faster and more stable W7 is. Way to go, at least for me.
I believe that you can now buy machines with W7 and if so, that's what I'll be doing next week.
