i've been a big supporter of dvds owning about 400 so far and for me blu ray is pretty much meh. yeah, it looks a bit better but overall there isn't much to really distinguish it from dvd. i certainly don't feel compelled to repurchase my old movies like i did when i upgraded from vhs to dvd.
netflix is what is really getting me excited specifically their download service. the reason i like buying dvds is being able to watch them whenever i want. now netflix has 7,000 titles available for immediate download and unlimited viewing. the idea that i could spend a similar or less amount of money per month and have access to EVERY release is soo amazing to me. oh sure, netflix doesn't quite have enough content yet but i'm certainly rooting for them.
...and in all honesty i'm getting tired of owning all these discs. do you realize how much room 400 dvd take up. well let me tell you, i'm on my third bookshelf and that is annoying.
...but if i had to pay per view - then i would hate downloading services.
MAIN POINT: unlimited content + not having to have physical storage >>>>> higher resolution.
