I have been looking into appleTV and I am currently converting my DVD's into itunes but I haven't actually bought an appleTV yet. Most of the time my PC that it will be running from will be on and connecting wireless. Because of this fact I am thinking about going for the 40GB tv. Is this what most people do? I just wondered what size of AppleTV everyone else has bought and why did they decide on that specific model? Also, I have a quick question, is there really any difference between connecting it via component over HDMI? Are they going to give me the same PQ? Similarly, do all AppleTV boxes have the same connections and spec ignoring the hard drive?
