There are big differences between downloading and instant watching or (online streaming).
And of course with these and a disc.
The online thing is supposed to be less expensive, but so far its quality is missing many things.
These 3 'ways' have their supporters and haters.
And depending on what quality means to you, or the rest of the world, these things are different.
It is obvious that many of us want Blu-ray support on our Macs.
But some only want to be able to read them, and many others would want to be able to burn them also.
In my case I would like to have everything, but unfortunately it isn't always possible.

When at home I do prefer to watch my videos on my Blu-ray player, which by the way also streams Netflix watch instantly. The best I can have is from the Blu-ray = 7.1 audio, 1080p on a 40" screen.
Netflix streaming depending on what is available sometimes I get excellent video quality ,but the audio is lacking perfection.
When I am traveling out of the country, my iPhone is my video player = rip DVDs, free podcasts, I hear in stereo.
For those that want to watch a Blu-ray on an airplane on a 13", 15" or 17" MacBook, you are not really getting all of it, listening a stereo soundtrack? Or are you carrying with you also your set of speakers?
In my priorities list, I would prefer is to have free Wi-Fi internet service on the airplane, and be able to enjoy all the free content available nowadays, and 2nd to that the Blu-ray on my Mac.
