Long copyrights aren't to protect older works, they are designed to protect newer works from having to compete with older works.

I agree this is a good thing, but until the infrastructure for internet connections are good enough to get the quality of video / audio you get out of blu-ray I still want the disc by mail option. The other part of this is that when you eliminate the disc by mail you also eliminate the commentary options along with other nice extras that the discs have which get removed for streaming. So I think that both services have good reasons to keep them.

Why herald the death of Blockbuster?
