I apologize up front if this is a tired question that gets asked a lot. My searches didn't uncover a great deal. Next weekend I'm getting an iPod Classic 120GB. My wife and I are running about 15 miles a week and I'm interested in taking the classic along with me. The HD concerns me though. All those impacts can't be good for it... But on the other hand I noticed that there are several arm-bands available for the iPod Classic. If they were made by Apple then I would take it as a sign that Apple considers this product robust enough to not crap out after miles of running impacts. I think most if not all of the arm-bands I saw were made by 3rd parties so I'm not making any assumptions.
