You'll know when these "unlimited" streaming plans really takes off: ISPs are going to be in front of congress going nutzoid.
If there was a $10 unlimited plan for the PS3, I might use it. The current costs per movie are still ridiculously high given the lack of materials, shipping, and handling. Not even to mention the fact that most people will toss everything when the system's obsolete (I'm sure the licenses have something saying you can't move them to a new system when you trade in your old game system).
I didn't even notice until i read this article that the change occured. I can say its about time! Now....they just need to allocate themselves bandwidth enough to be able to stream HD movies for me :)
