And it's everywhere. I've been on the road a lot the last few years, all over, central/south america, north america, korea, europe, airports, trains, coffee shops, restaurants, hospitals, it's everywhere. I've taken to spending time to just sit somewhere for a half hour and just watching people...stuck, totally glued, to the screen. So sad to watch parents with children, the children desperate for attention, the parents zoned into the device, or the inverse also...but the degree of prevalence is stark to my mind.
