I am trying to find out what PS3 to get. I would like to, at the least, have the 80 gig. If there is one that is better I will also go with that. But I don't want to sacrifice anything, such as the built in Wi-Fi, the 4 usb ports, and the card readers. I would like to get the most. I am going to put lots of music on and movies and demos. Just to show how much space I am going to use, my iTunes library has about 8 gigs of just music, thats without movies and all that. Movies I have about another 20. SO.... please help.
