Nice, but...
All very nice and I'm sure it will be just want some people want, however I don't want to faff about with easily broken discs. I have kids and despite how much to moan and shout, kids and discs do not mix very well, indeed kids and tech don't mix that well unless the tech is toughened. I want my content to be stored in one easily accessible place, I want it in a format that can be played on almost any device with the minimum of fuss. I have to jump through some hoops to get my DVD content into file formats that can be used on multiple platforms but I know when I am done it's instantly available, relatively kid-proof yet easy for the whole family to utilise.
The quicker the media companies start to understand what most consumers really need to do with their media content, the better things will be.
