Tommorrow (morning?) the beta for XNA Game Studio Express should be available for you to download!

I'm going to do a video capture of the Gamefest demos I did so you guys can get an idea of what the component model looks like and some of the things you can do.  Of course I expect to see way better components over the coming weeks from the community!  As mentioned earlier I'll also post a tutorial walking you through creating a component that displays the frame rate for your game.  Just drop it onto your game and you're done!
