I enjoy the digital copies even though I have a portable DVD player myself. Sometimes I'm at school or something, bored, and I just pull out my iPod and watch a movie. I don't bring my DVD player with me everywhere.
It is a cheap near-false advertisement calling it a 3-disc edition though. Hellboy II did the same thing. If they're going to call them that, the least they can do is add a couple features to those discs, like what I Am Legend and Zohan did.
As for the Norton cut, the deleted scenes on Disc 2 are all finished and look nice so I'm really not disappointed anymore that the extended cut wasn't included on this DVD.
