Meh, I don't see much difference, and I won't kid myself into thinking that I'm actually "purchasing" anything from either of those services, rather than a semi-long-term rental at a higher price. I'll stream DRM video for a cheap monthly fee but I won't "buy" it since it's never mine, given that the purchases can be rendered worthless at the flip of the service provider's switch. If I want permanent access to a movie, I get the shiny disc and rip it to a standard format.
