Hello, i have a very organised i-tunes library on my Macbook, and i currently play all my **** through frontrow 2.0 into my LCD TV, im worried that doing this all the time is shortening the life of my Macbook as it seems fairly intense work on my harddrives. So here are a few questions.... thanks in advance. if i take the plunge and get Apple TV will my Macbook be releaved of the pressure and keep my macbook a cool temperature??? when using Apple tv can i use my Macbook for other things like using the WiFi to surf the net? or does ATV clog the airwaves? what other advantages does ATV have over Frontrow 2.0? Does ATV need to join my home network or does it run on a private network to the Mac? And i take it that ATV plays anything that Itunes does? as i have all my movies referenced to an external HD so i dont have to encode them to Mpeg Whatever????? for life.
