When people have workflows it isn't convenient by definition...
Bla, bla, bla. First i have only 16 bluray discs and I add 1-2 every 2-3 months. Most evenings i like to watch something that would mean putting disc in and taking it out many times (fingerprints, dust and scrathes). Now i have everythin on iTunes and WD TV HD with no need to change discs or look for them. I still see no point why i would want to watch bluray on my iMac, i have tv for that if i want to.
