Apple TV - H8xOred!
Non-Apple TV owners can enjoy the out of box experience by viewing the opening video which one crafty person ripped from the hard drive and posted in all of it's 720p glory. You can also download the Quartz Composer Screen Saver and the Now Playing Screen. And if you're truly hard-core you can download the entire Apple TV OS, and (conceivably) install it on another Mac.
And apparently that was just the easy stuff.
