I have a Mac mini hooked up to the TV in my living room. There are plenty of good uses for this, but I find it odd that this $1000 device can't perform some of the functionality that the $100 Apple TV does. Is there an application that runs in OSX that basically emulates an Apple TV on my computer? I could just buy an Apple TV. I'm not really struggling with the $100 price. The problem is that I'd then have yet another device plugging into my TV, and I passionately hate having to toggle through my TV's inputs. I want one device that does everything so I can just leave the TV set on that one input.
