I was invited to an event the other day where there were a lot of very wealthy people; Bank presidents and their investors. Open bar, free food, free valet parking and coat check. While in there mostly being a wallflower (because I am not good at this sort of event), I happened to notice that nobody was sitting there staring at a screen. In fact, I heard no alerts, no ringtones, and saw no trusty smartphones strapped sturdily to the hip. Nobody pulled a cell phone out to check the time, or the weather or their messages. During the entire three hour event I saw exactly one of these people look briefly at a cellphone. It was a smartphone, but a very early model with a small screen, and looked well used. She glanced at the time and put it away.
Not drawing conclusions, just something to ponder.
