Anyone using one yet? Any opinions, comments, rants, anything? :)
This is a recently released accelerometer / pedometer type device that is designed to go into Nike Plus + shoes which have a little pocket for the transmitter (but it can theoretically be used with any shoe). The official name is the Nike + iPod Sports Kit. The kit contains the little chip (transmitter) and a wireless receiver which plugs into the bottom of an ipod nano (ipod nano only supported right now - no other models). The nano receives the information during the run...and displays various statistics on the ipod screen. It can also be configured to give various voice information to the runner during the run (through the ipod headphones). Once the ipod nano is synced with itunes on the pc/mac the data is then present in itunes somehow..and gets sent (automatically?) to nikeplus.com which allows the data to be viewed, tracked, etc. It appears they're implementing some "community" aspects as well but it isn't implemented yet. The product also changes the middle button into some sort of "power song" button which when pressed plays a preselected song (theoretically one that will motivate you to pick up the pace.. :) ) They claim > 90% accuracy for most users w/o calibration, and increased accuracy with calibration.

I wonder if Apple is subsidizing the product.. if it is really an accelerometer + the wirless transmitter, r&d, etc, it seems it would be more costly than $30.
Assuming it works as well as advertised, it seems like a good (and quite a bit cheaper) alternative to a garmin forerunner or other GPS product, especially for someone that regularly runs with an ipod anyway...and no laptop strapped to the wrist.
Here is an interesting white paper on the technology used in the adidas / polar product, I'm not sure if it is the same technology or not? http://www.dynastream.com/datafiles/SpeedMax%20White%20Paper%20v4_1.pdf
Is anyone using it with non Nike+ shoes and how did you affix it to the shoe?
