I've had my Apple TV for a week now, and I've pretty much got the grasp of it. However, there is little features and tricks I'm still finding! I'm curious to hear what you couldn't live without. I love how I can have the Apple TV turned on and TV on, and open iTunes and play some music and the song details just appear on the screen. That is reaaally cool. Also, the YouTube integration is really cool. All my friends are jealous of how easy it is to do stuff!
