I came across this wonderful little cheat sheet today while I was browsing the web during my lunch break. It's a cheat sheet for making the transition from XNA 3.1 to XNA 4.0. I know most people have already made the jump, but I'm still the stubborn fool in the back sitting in the dark, comfortable with 3.1. I'm going to make the move to 4.0 really soon, and even redo some of the projects I've already been working on. This cheat sheet is definitely going to make things a little easier, and I hope it helps others out there as well.
