Someone told me once, "The best thing that ever happened to Voice of IP was cellphones." That can be debated but the premise was essentially the same. Once you get used to a lower quality, and I would add that quality becomes pervasive, then something better has an battle on it's hands. Blue-ray is more expensive and DVD's, streaming media, online movie rentals, and home delivery rentals are pervasively distributing DVD quality. Do I want to see the movie or do I want to see the movie on Blue-ray? I just want to see the movie. No one is going to ask you, "Did you see that movie on Blue-ray?"
