Visual Studio 2012 Best Features

I find it interesting that Visual Studio is the only Microsoft product developers automatically upgrade without giving it a second thought. So I'm trying to develop a Store app using Visual Studio 2012.
What are the significant helpful experiences or challenges encountered with Visual Studio 2012 Best Features?
I'm excited to use the new Evil Code Monkey feature that's now included in IntelliSense. This will point out your ugly code, and allowing you to Google the correct way to write it. I find it very helpful since after copying and pasting codes, things can get messy so this feature can make things easier for me.
