Not directly related, but this post made me think of our evolving "need" for ever more technology in our everyday lives. When using apps becomes as mainstream as having a mobile phone or having internet access at home, even those of us who think we get along fine day-to-day without apps will, I think, come to believe we need them to function, just as I now think I could not live my life without reliable internet access.
Good point: 30 years ago, who knew they needed a phone with them at all times? Now we can't live without one and, increasingly, the apps on it (like maps, restaurant reviews, and movie times).
