If you want to green up your tunes manufacturers are beginning to capitalize on the energy in the world that is just hanging out and not being optimally used. Somewhat like the cranking mp3 player featured before, Thanko has created a personal media player that can charge with a little less effort your part. Without the suggestive cranking, the solar powered PMP gets about 30+ minutes of play for every hour of charge. If you jam the tunes all day you might need to get a couple of them. It has some games preinstalled and an SD expansion slot for those long walks.
4GB for $95 and you never have to buy batteries or a replacement charger.
