Love it.

Mind, I'm not too keen on VS 2012. I've went back to using 2010. I'm really not a fan of the way Microsoft is starting to design some of their applications, with that weird Windows 8-ish style that VS 2012 carries.

Everything just merges in to each other because they're all different shades of white, and it makes it hard to figure out where everything is. It's really not easy on the eye either, and that's a big deal when you're trying to focus on something.
