How long will the battery last?
Similar to iPods, the Sport Kit's battery will not be easily replaced. So how long will the battery last, and therefore how often will we have to replace the Sport Kit? Although there are no detailed specifications on the battery life of the Sport Kit, a May 24th article in BusinessWeek sheds some light:
Other technical challenges centered on the duration of the battery power (close to 1,000 hours).A thousand hours of continuous operation is less than 42 days. The Sport Kit will certainly last more than a month or two. Therefore it's a safe assumption that the battery will only be drained while actually in motion and sending data. This theory is affirmed by a commenter on engadget.
Dr. Pribut, a Washington DC podiatrist, recommends getting new running shoes every 350 to 550 miles. At a modest 10 minutes per mile pace, this equates to 58 to 92 hours of running. I personally don't replace my running shoes this often, but perhaps I should. Doubling this time for warm-up and cool-down, we get 116 to 184 hours of time spent in each pair of running shoes.
In conclusion, it looks a Sport Kit will last through at least five pairs of running shoes. With only a $29 price tag, this sounds perfectly reasonable to me.

My nike + ipod sensor lasted less than a year. I averaged about 15 miles a week for roughly 9 months. It was a neat device, but I am not going to purchase a replacement.
Fortunately, I had a little better experience. I've logged over 1200 miles over the last 12 months with my sport kit battery dying just today, almost a year to date since it was purchased and immediately put to use.
