Has anyone tried it out meanwhile? I think that this cloud approach is a pretty promising deal, because personally I grow tired of always carrying around Terabites of data. Do you think there will be a limit to how much data volume people will be able to carry around? Or will millions of people be able to carry the library of congress on their smartphones in a few decades?
I think not, and that the cloud has the ability of making some kind of hyper-brain, like the ultimate online music collection. Companies have already recognised that, and some are able to make decentralized operations world wide while still acessing and improving their database. So why not do the same for entertainment media? If the preice is affordable you could easily get enough consumers together to make this kind of business worthwhile.
