What are you thinking of tracking and what kind of use do you have for the information?
I've found that my iPhone does just about everything I need from a GPS system. Provides guidance, tracks location, calculates averages speeds, elevation gains, tie in photos to geograhic location, etc.... The only thing it can't do is provide updates to some of the tracking services like Spotwalla if you want people to be able to follow your routes. If you want coverage outside of cell towers you need a SPOT tracker that sends locational info via satellite or something similar.
If you want to use an iPhone as a lap timer you can buy an app (there are several) that will give you lap times, split times, speeds, lean angles, g forces (lateral and acceleration), and so on.
Don't know if that helps, but I get everything i need from an iPhone, and have a SPOT tracker for when I take long range trips.
