For some time now I’ve had a Mac mini connected to my TV and I love it. Everything that plays on the TV goes through the computer: Live television (via a tuner), DVD playback, music, music videos, streaming TV shows, streaming movies, photos, etc. Great little HTPC.
However, I’ve been constantly struggling with the 10-foot user interface. The built-in Front Row is too limited for my needs. Sure, I can do everything with a bluetooth mouse and keyboard; but it’s hard to control the regular Mac OS X interface from a couch. My eyesight is good, but not that good.
