I also really like the Netflix idea. It was really easy to set up kind of... I'm on the last step! You have to activate it from your computer using a code that your Xbox gives you. It won't freaking work! I called netflix's free 24 hour support and they said their server is getting hit really hard. So maybe try later? It's funny how when MS doesn't screw up an update, Netflix does haha. The avatars are pretty funny. More customizable than Mii's and you can take a pic for your gamer card!
Edit: You can't make the avatars very short... or fat!
My kim jong il looks nothing like him. :(
