Apple TV and iPod touch
I just loaded the iPod Touch app that makes your iPod a remote for your Apple TV. I can see my whole library that is on my apple tv. You can browse your library, choose albums with artwork. I don't have to have the display on.
I then posted this through my iPod Touch while listening to the music. All this through a device a little bigger than five credit cards stacked on top of each other. Wow, how cool is that. If you have an Apple TV and a Touch, you have to give the remote app a try.
