Here's an odd but interesting combination. This week, Apple Computer announced a new iPod add-on called the iPod Sport Kit. Once you have the complete set—an iPod, the add-on, and a sneaker-based sensor—you can work out and get data on your progress in real time. The software provides voice-based information, including training data and even inspiration if you seem to be falling behind in your workout. (I'm imagining something like, "Let's move it, fatty!") Furthermore, a new Nikeplus.com Web site can track your workout progress over time, so you can see how far you've come. Not too shabby, I guess. And it's certainly a huge indication that the iPod is a hit with the mainstream and not just the techie geeks that typically flock to Apple products
