Good commentary on the Sprint cell-phone commercial: Adults in a waiting room are climbing the walls and twisting their bodies into silly poses in desperate efforts to pass the time. What they need, the ad says, is a cell phone with cool video games built in. They'll never be forced to endure downtime again! The commercial captures a characterization of modern Americans that has become so generally accepted that we don't even question it. We are people that, the assumption goes, like lots of fast-moving, shiny things. We must be entertained and occupied at all times.....We are, if you believe the marketers, no longer a Prozac Nation but a Ritalin one.
