Two months after a joint announcement by Apple Computer and Nike, <A HREF="http://www.ilounge.com/index.php/ipod/review/apple-computer-nike-ipod-sport-kit/">the Nike + iPod Sport Kit</A> is now available in stores, along with a variety of compatible Nike+ ("Nike Plus") shoes and clothes. Designed to work only with the iPod nano, the Sport Kit consists of a small red and white wireless 2.4 GHz sensor/transmitter, and an all-white iPod nano receiver, which together track and store data on a runner's or walker's performance for later synchronization with iTunes. In order for the kit to work as intended by Apple and Nike, the sensor must be inserted into a pocket within any Nike+-branded shoe.
