Where once such devices were relegated to appropriate times, now they've become necessities. The other day I watched a kid come off the school bus listening to music on his headphones, oblivious to the traffic zooming past him. And I can't even begin to count the times I've thought pet owners were talking to their dogs while taking them for a walk when, in reality, they were blabbing on their cell phones. It's a different level of use than we've seen in the past, ... It's becoming more of a full-day listening experience as opposed to just when you're jogging.
