An electronic compass uses battery power and is an extra expense for a feature that you rarely (if ever, depending on the use case,) will use. It requires calibration and is prone to interference. It is no better than a standard magnetic compass.
If you are going to be standing still a lot and trying to figure out which direction north is, then get a regular compass. If you are using the GPS to track the typical things that one wants to track while bike riding, or motoring to one's favorite fishing spot (the use-cases that Jim said he wants it for,) then the electronic compass is a drawback rather than a feature (it reduces battery life without adding information.)
