Anyone else have this problem? I have a 1G nano that was replaced because it was no longer responding. The one they sent me works fine, however it is noticabley dimmer. No where near as bright as the original one I had. I don't think there is a setting to adjust this either. I am going into NYC tomorrow, do you think I should take it to the iPod genius bar...maybe they will replace it? Or is this not covered? Let me know your thoughts.
