Thomas Brand leaves his iPhone at work in the evenings:
This division keeps me on task at work where I need to stay connected, and attentive to the people around me when I am at home. Not everyone can do this. My job pays for the my work phone, and by running to and from work means I don’t need to stay connected while commuting. I may miss the company of my iPhone while waiting in line on the weekends, but I make up for it by spending more time with my wife.
I like it.
