Conclusion: With its great community features, the Nike + iPod Sport Kit adds an extra element to running and walking that can actually inspire and motivate you more than simply listening to music and timing yourself.
Pros: Fun to use. Easy to set up. Excellent community features.
Cons: iPod's Select button can be difficult to find by feel, so either buy a Nike + Sport Armband or get an adhesive felt patch for the button. Works only with the nano.
