At a recent Ben Folds concert, during Duncan Sheik's opening act, the audience started waving lighters to the music, points of yellow light flickering in the time-honored ritual for power ballads. And then blue lights mixed in with the yellow: people were holding up their backlit cellphones. In a post-tobacco, wireless world, when Freebird plays, people will flip open Nokias, not flick on Bics. I have seen the future, and it is electric blue.
