Again I'm confused. itunes is perfectly usable with my 42" plasma (even from 3m away) and my bluetooth keyboard and mouse just make life simpler.That is exactly what i dont understand. iTunes app doesn't have an interface built for browsing from 3m away. And keyboard & mouse don't exactly shout couch friendly. The only software on the Mac Mini that is built for using from the couch is Front Row. And that is just for media consumption
If there's something my mini cant do that the appleTV can then I'm all ears but I honestly believe if we made a list it would be skewed heavily in favour of the Mini.
