I can not believe the ignorance of people on this subject. Have you actually owned a LED HDTV with a blu ray player and a 5.1, or 7.1 surround system hooked up to it? It's BREATH TAKING. Every time I play a download from iTunes or use Netflix, I'm like "this is blah". Then I pop in a Blu Ray disc and I am immediately blown away at the picture quality and the audio quality. Especially audio. Uncompressed audio just sounds so much better to the human ear then compressed does. I mean sure if you use the right compression standards it can come close, but there is something about PL II, THX, and the other audio standards on a high quality surround receiver that online video can't deliver.
So anyway, yeah, I don't necessarily think we need these in our computer, because let's face it we're not going to watch these high quality movies on a computer, we want to see them in the living room. So really, why do we want blu ray in our computers? So we can pirate them of course, which is exactly why Apple doesn't put them in their computers, AND exactly why Apple doesn't let you sync your ipod touch, ipad, or iphone with more then one computer, wouldn't surprise me in the least bit if all these ways to circumvent copying are actually part of back room agreement with apple and hollywood to get more of them to be on board with selling content digitally.
Myself, personally, if I LOVE a movie, I'm going to buy it on Blu Ray. When it goes on sale on Amazon.com or at Target, it's usually CHEAPER then iTunes anyway and I don't have to wait several hours to download it and waste all that hard drive space...
