As somebody who seldom carries a mobile phone, figures out local directions with an address and paper map, etc., this editorial resonates strongly with me, and the author illustrates his point beautifully. His expression, "diminished substitutes," captures a feeling I've had for a while about the 4G lifestyle, or even one that just takes place too much on the internet.<p>In the past 3-4 years, when smartphones completely hit the mainstream, I have noticed a very significant change in those around me, even in some people I am close with. They seem more ... robotic! I am certain if I moved in different circles, I would've noticed a similar pattern years before among BlackBerry users, who were the butt of the "CrackBerry" joke ca. 2004.<p>I'm not sure how else to describe somebody completely fixated on a small device, resorting to it almost like some security blanket when an everyday problem needs solving. Portable video games like Game Boy, and traditional mobile phones, which no doubt have been similarly derided in the past, offer a poor comparison for their limited scope. The small screen provides some strange tunnel vision I don't care to encounter.
