I can't fathom how anyone with good visual acuity and the money, who enjoys films, doesn't have a BD deck of some kind. The image quality (and audio quality, although I don't have the ability to exercise that because of where I live) far outweighs all other downsides to the format.
Very happy owner of a PS3 and the 360's HD DVD player here. My eyes are in love with the IQ.
