"It's got a good beat, I can run to it, and I can compile and share important data about my exercise regimen, too." -- Runner using a Nike+iPod Sport Kit, 2006.
Music, physical movement, technology and being cool have long gone hand in hand. Now, two iconic brands, Apple Computer and Nike, are collaborating on a new system of gizmos that take exercising and digital-music players to a new level. The Nike+iPod Sport Kit allows runners and walkers to listen to songs and to record, store and share information (such as speed, distance covered and calories burned) with others about their exercise sessions. The system also "talks" to runners in real time, providing information as they jog along. The $29 kit consists of two gadgets -- a receiver that plugs into an iPod Nano and a sensor that sits inside the inner sole of specially made Nike shoes and transmits data to the receiver wirelessly. Buyers also get software to download the running data to a special website where the information can be stored and tracked over time and shared with other runners.
