i think if they can apply this to some sort of movie download service on the internet were you can rip it straight to these disks and perhaps single DvDs may become a thing of the past. And soon we could have one DvD sitting in our players "Hey honey what movie will we watch" and just flick through almost endless amount of movies.
My oppinion this could be amazing if they work around the faults it may/will have for instance:
Be able to update the amount of movies you have on it at any time
some sort of software for it (dumbed down version)
also a way to put your old DvDs onto it. cause i have over 500 films on DvD and im not waving goodbye
