(On the train home, last night:)
Of fifteen people near me, on the same seat or the one across from me, three people are not plugged in in any way. (I am plugged in, but not to the network, so maybe that's four.) By plugged in, I mean, earplugs inserted or cellphone or some other electronics out, and actively using the device.
One of the three is reading smartphone ads from docomo.
I am reminded of some science fiction scene in which everyone is plugged in to the indoctrination station.
Maybe Fahrenheit 451, but portable.
