Hey, i'm about to buy a ps3. I was wondering how much of a difference there is between playing on a regular tv, and playing on an HD tv with HD cables. If so, what cables do i need, component cables? Also, can i hook this thing up wirelessly, or do i need to use the ethernet? What are the controller cables for? do they charge it? if so, how do i do that? Is there a standby mode like the ps2 had, or do i just use the switch in the back? Also, what is the PSnetwork. i see you have to sign up for that. does it cost money? thanks, sorry for so many questions.
