It's too bad they don't have GPS but maybe tower location is good enough. It would be cool as anything to have these get cheap enough you could attach one to every runner's bib in the New York City Marathon and watch the resulting data set. I could see both real-time location services (where's my wife on the course?), cheating prevention (why is this tag in the back of a taxi on 8th avenue?) and so on. People would probably pay $5-$10 extra to have that attached to their bib for their family to see. Sure you can accomplish the same using any number of iphone / android tracking apps but they're all battery suckers.
