Hi, I was just wondering how reliable the ipod mini is while jogging? I know the armband must work pretty nicely, but my question is how long can it last since it has moving parts? I heard flash players were the best for working out, however I would love to buy an ipod mini. I just want to make sure I don't break the little thing while running my normal 4 mile run. I've never owned a mp3 player, so I'm not quite sure how much wear and tear the hard drive would take considering it's being bounced up and down for 30 mins.
