I made the switch. I wanted to reformat, anyway. It just seemed like a good time to try something new, especially since I never really make OS switches early on.
After installation, I would say in getting used to going back and forth between Metro and the desktop, I actually find myself utilizing most of the search functions and accessing programs much quicker than on Windows 7.
I can't say the switch was hiccup free, as I had quite a few things to tweak to my liking, but I'm not upset about the switch in any way. It's fast as hell, as someone mentioned.
