I just got back from using the new iPod compatible treadmill! Wow, its really cool. You just plug in your iPod with a cable connected to the treadmill, and your headphones into the headphone port on the treadmill. Then you select the iPod, and it looks almost identical to the iPod menus, you control everything through the treadmill's touchscreen. Pause, Play, Volume next. Its really really intuitive! It made my workout a whole lot easier, I didn't have to keep grabbing the iPod to change songs or turn up the volume.
