I think there is something different with mobile devices though, I've seen kids using iPads before and they barely manage a couple of minutes in one app or game before they switch out to another. I really how this sort of behaviour is going to manifest when they grow up, are we heading for a generation with zero patience and attention span? I see it even in adults these days.
One thing I got really good at as a kid was being patient. When waiting for an appointment, I'll usually sit there and wait without staring at a screen. It's nice to have a few minutes to just do nothing.
