I only use my iPod at home or in my car. I have an Alpine stereo system that you can plug the iPod directly into, so I don't worry, I am NOT driving with earphones on! When I used to take public transportation, I used to take my portable CD player with me. The buses are so noisy, nobody really notices if you have it turned up a bit. I would never use my iPod in a library or any other place where quiet is expected.
