There is no advantage in buying bluray lol
dont give in to sony's HD bluray! its going to be dead in a few years and youll see the same bluray you paid 30 bucks for, in the discount pile in walmart for 5 bucks...like all the DVDS now...its faster with bluray because EVERYONE watches things online now, or download/purchases online. Its fast and convenient. Have you noticed less and less video rental stores?
And you can download quality just a good as bluray, which has no expandability to a better format, unlike streaming or downloading it online.
