The REAL bottom line isn’t even whether the quality of streaming is as good, or even better, than physical media. Many of the people that have posted here are not only movie lovers, they’re “collectors”. If you don’t get any physical media than what’s the point? People used to buy records or cassette tapes? The only reason that market is virtually gone is because those people now download them for nothing...or at the least, very cheap. They wanted to be able play them anytime they want to, not when they happened to be played on the radio.
I don't think that's entirely accurate. I don't even really think of myself as a "collector" as I don't usually buy things day and date on release, and honestly, as I've just stated in my previous response, I would be willing to move to purchased files if the DRM was removed and the quality was similar to blu-ray.
Up until very recently I purchased all of my music on CD and then I ripped it and imported it into iTunes. Now that DRM is no longer forced on me with downloadable music files, I am becoming more willing to purchase digital copies and simply back them up on my NAS so that I will have my own backup copy.
Something similar would have to happen with video for me to make the move, but I don't see the studios budging on the DRM thing.... even though the parity with music as far as piracy, etc, is almost 100%.
I personally find it somewhat frustrating that so many of the advocates of streaming and DRM laden downloads, refuse to acknowledge the problems with DRM device locking, service locking and all of the other disadvantages. If you like the convenience of streaming, that's great, but as a responsible consumer you should at least acknowledge some of the problems with these services as they are currently being delivered.
