This may be the first generation not to know what it means to be alone with their thoughts.
We grew up knowing what it means to drive a car or go for a walk without a companion, or without inevitable electronic interruption. This generation doesn't and I'm not sure this is a particularly good development.
I've long been convinced that so many people are constantly distracted from what's going on inside their own heads because they can't stand to hear what's going on inside their own heads.
For many, iPods were, remain, and will always be the greatest invention EVER.
