I heard about it on NPR. I don't think it will replace Netflix as, as I understand it, you have zero control over what content it puts on the box. It just always has 100 movies on it and they get cycled out. A very cool concept, though. I think that it's exactly a lot of people will pay for. My parents would probably enjoy it. Plus, it's over-the-air. No internet bills or anything.

You're only allowed to watch the rented movie for 24 hours before you have to rent it again.
