GPS devices like these are obsolete already. Mobile devices showing at CES have everything in the way of GPS and monitoring of body functions such as heart rate and temperature. The only thing currently missing is a bluetooth enabled cycle computer which is in the works. Monitor your heart rate, speed, location, listen to turn directions and power output and cadence at the crank all on your phone plus connectivity with with the internet by way of cell phone, bluetooth, and WiFi. Of course there is a camera as well!
