1984, quite the read. While the Apple ad is not entirely related the article touches on an issue that has been in the news (though largely under reported) which is mass surveillance. This cloud in this case in an enabler to mass surveillance, while not the ideal use case it should be noted and addressed none the less. These issues need to be fully fleshed out and talked about before the cloud can be envisioned in its entirety.
I have included this article to bring awareness to the fact that cloud computing can also be used for nefarious things. http://thecreatorsproject.vice.com/blog/gif-six-pack-endless-sci-fi-to-celebrate-1984
