Just curious what you're running. I'm especially curious on those running Vista--are you running 32bit or 64bit? Feel free to explain your vote if you'd like. I've allowed for multiple votes for those that dual boot and/or run multiple machines.

I'm currently on 64bit Vista Home Ultimate, but I'm not sure if I should revert to 32bit, since I don't have any 64bit app's to run. Not sure if there's a benefit at this point, so what does everyone think?
