Great post. I love to run with my iPod only (I need music to drown out the sound of me struggling for air), because it doesn't allow the interruptions that my phone does. It's nice not being able to be reached constantly, there's almost a weight that falls off your shoulders when you know it's just you and your thoughts. Once you get past the ideomotor response to constantly check your phone, there's a sense of freedom that comes over you when you're untethered from your cell.
