I ran the Consumer Preview, and I'm glad I did, I didn't have to go through the curiosity of what I'd be getting myself into running it on one of my machines and not just in a VM.

I stuck with Windows 7 on my gaming rig, and on my laptop I switched over to Ubuntu with Gnome.

Anyway, I wanted to say if you're going to stick with Windows 7 for what might potentially be the rest of time, please do the rest of the world a favor and don't run Internet Explorer. I prefer the non-profit built Firefox, but even Chrome, or Safari for Windows is a better choice than IE. Firefox won't be tracking you in weird unknown ways like Chrome may be, but all of them will give you better security and a more advanced web to enjoy.
