Two huge brands have collaborated on the Nike + iPod. If you are a runner and bring your iPod Nano with you, then you can add pace, distance and time statistics with this device. Put the pod in the insole of your shoe and it will beam its stats to your Nano display. The Nike + iPod sport kit is only compatible with the iPod Nano. Press the center button to hear your pace in a spoken voice (your choice between a generic male or female voice). There is a celebrity feedback feature where either the voice of Lance Armstrong or Paula Radcliffe will congratulate you when you achieve a personal best.
You can view run or walk history from within iTunes, and you can upload your data and share and compare results with the community at the Nike+ website. There has been privacy concerns with this device as your position can be intercepted by an RFID receiver.
