Yeah, I would have a much harder time finding anything if it were all in sleeves somewhere.
Though I suppose a computerized DVD/BluRay jukebox system would be cool ... one that would also skip all previews, trailers, game ads, menus, FBI warnings, THX sound alerts, and even stupid studio logos for the 6 companies that nowadays present a single film ... if they are going to be immediately followed by title cards that repeat the same information.
Actually, the thing I am most impresssed about the Prisoner of Azkaban bluray I just bought is that after a single FBI warning, the movie just begins. No menu, no ads, just the movie. Love that.
