i was just wondering if jumping up to the 160 gb Apple TV is worth it! the 40 gb one is pretty good but for 100 dollers more i could get like 400 times the capacity!! but i was thinking that im pretty sure i would never use 160 gbs of that! could i add an external hd to the tv? if not then could someone refer me to which one would be better!!! thanks alot guys!!!!
