It's cool because the map colors are more simple and it's easier to see the streets and stuff. And it marks streets with bike lanes in green which is helpful when venturing into areas where you haven't biked before. Unfortunately the bigger aspect of the tool which is directions on bicycling won't be available on Mapper, unless someone can find a way to export google directions and import them in Mapper. Supposedly the directions account for bike lanes, large unfriendly streets, and even hills so that you're not going up a giant hill when there could be a better route.
