iTunes Movies VS DVDs

Movies have become more and more popular on the internet. We can thank youtube.com mainly in part for that. But copy righted movies are also up and coming through Apple's iTunes Store. Large film studios are offering downloadable movies (with a catalog of over 500) to the online store. Such companies include MGM, Walkt Disney, Paramount Pictures, and Lionsgate Entertainment. This, I belive is one step closer to eliminating illegal downloading through the internet, but at the same time, it makes no sense to me. People most often buy movies for the sake of having the case along with it. For instance, I don't think I would buy a strictly downloaded version of Sex and the City to keep without the cover. It's kind of like an episode of there where Carrie goes to a party and is asked to take off her shoes before she comes in. Her response is, "But this is an outfit". It's part of a whole. It is part of what makes movies like The Godfather or Scarface a classic. Music is different, because there is so much more of it, and also the size is extensively smaller than movie files.
