I'm considering purchasing an Apple TV for the Family Room. However, I'm curious whether it might be worth it to spend a few hundred dollars extra to purchase a Mac Mini to hook up to the TV (my TV has a computer input). I would like to play movies, TV shows, and music through iTunes, as well as display photos. I currently have a new Airport Extreme-n wireless network that can accommodate a hard drive on which to store most of my media. The added benefits of the Mac Mini are obvious (fully functioning computer). What functionality, if any, though, will I be missing out on by not having the Apple TV? Thanks for the advice.
