Bob,
Sometimes it's nice to get rid of all the clutter in the satellite view and take a look at where you are with the map view. The other reason I'd like a map view is for the screen shots I send to the RD. I think they are more used to seeing maps in map view, so they would like it better. Not a big deal though.
Does anyone know if mapping websites besides mapmyrun and google earth allow you to import and export routes (gpx or kml format)?
