Excerpt: I decided my 2009 New Year's resolution will be to get in shape with a Nike + iPod Sport Kit. The combined efforts of Nike and Apple enables iPod nano/Touch owners to slip a sensor into their tennis shoes and get a fitness trainer. The iPod Touch has a built-in receiver and support for the Sport Kit. Owners of iPod nano 4th generation need to insert the included wireless receiver into their dock connector.
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.

Pros: Pedometer battery is not replaceable, For iPod nano only
Cons: Good workout companion for nano-using runners, Voice feedback, Measures useful data such as distance travelled and calories burned, Special Nike + shoes are not a requirement, Excellent hardware and data integration with Nike + Web site, PowerSong
