Hi, I just got a 40GB Apple TV off eBay. I am wondering if this was a bad decision (vs. buying a new 160GB one) - not because of the extra storage (storage does not matter, I am planning on upgrading the HDD anyway)... I am wondering: Are there any differences, hardware wise, between the old 40GB version and the 160GB version (other than the HDD). Also, the guide posted in this forum is for a 250GB hdd. What's currently the max. HDD the Apple TV would accept? And are there any other hardware upgrades that are possible? (what's that HD card all about for example?) EDIT: Also, what accessories does the Apple TV usually come with when you buy it NEW? Thanks, chris.
