Is there really much difference? I've used AirPlay on my iPad and my ATV, and it's pretty awesome, have yet to try it on my MacBook. Now, because I have ML and a late 2011 MacBook Pro, I can essentially AirPlay all my music through to Apple TV, therefore, do I need to enable Home Sharing? Is there mush of a difference in quality? I tried Home Sharing on my iPad and my ATV and it was good, though I prefer to use the actual remote.
