The Nike & iPod Sports Kit places a tiny sensor in your Nike+ Sneakers and sends a wireless signal to your iPod Nano, turning it into your personal coach and trainer. With a variety of workout options at your disposal, the iPod Nano displays your progress such as calories burned, time passed and distance covered, all the while playing music. Over the iPods headphones your virtual trainer informs you of your progress, as well as giving you the proverbial pat on the back when you reach a personal best.
