Nike+iPod Sport Kit

Runners and walkers, whether casual or serious, should find a lot to like in the Nike+iPod Sport Kit. Although the package doesn't provide enough data (for example, heart rate or split times) for the most hard-core competitors, it does provide plenty of motivation, enabling you to enjoy your tunes, receive audio feedback with the press of a button, be part of a community, and see how well you're doing -- both against yourself and against others. The Nike + iPod Sport Kit is simple but ingenious, easy enough to use for beginning runners and technophobes alike, while reliable enough for even competitive runners.--Jeff Merron
