HD is awesome and i agree, it's hard to go back to SD. the only thing i can forgive it for is old things like seinfield that were around prior to HD.
also, i just got back from avatar 3D and as much as i said to myself it's going to be meh it was totally f*$#ing awesome. anyone have a link to the whole blu-ray 3D specs thing cause i really want to see if i'm going to be able to bring that experience home.
