So, I stumbled across something useful for us bikers.

I thought this would be useful for us bikers... until i saw the price. 
A GPS watch.

Made by Suunto, this is the world's smallest multifunction GPS watch for wilderness navigation. It uses a text display of latitude, longitude and waypoints, and it also has an altimeter, barometer, thermometer, and compass.

I would just get a tomtom but this might be nice for someone who's got the cash to burn.
