Yeah.. Those are some things to do with it.. But, I only have one. Lol. I don't need anymore than that. I am actually thinking about buying the OLD Apple TV to keep along with my second generation TV. This is because It has a hard drive. It's not cool how the new one doesn't have any real storage. I mean yeah, airplay is awesome. But it's laggy.
The main reason for getting the old one is yes, because it has a harddrive. I find it a bit much to have my macbook on, open, keep it form going to sleep mode, being connected to the same Wi-Fi and have iTunes OPEN just to play something on it.
