Ran Vista home premium for a couple of months. I quite liked it, there were many many good features, but the problems drove me mad. Couldn't get my Creative X-fi soundcard to work properly, Firefox had some problems, bluetooth rebooted the computer each time I plugged it in and a lot of my usefull little programs that you collect over the years didn't work. I'm now typing this on a fresh XP media centre installation. Both my sons did the same. I'll wait until SP1 before reinstalling.
