The Nike+iPod system has been a great idea from the get-go: Use this music machine not only to play tunes while you run, but also to measure your time and distance, provide audible updates on your stats and keep track of your progress over a period of weeks, months or years. Even if you’re a purist who shuns on-the-run music, you might get something out of Nike+’s other features. The only problem with the original setup was that it required a bit of extra gear. Have a favorite pair of running shoes? Toss ’em, ’cause you’ll need a new pair of Nikes.
