Here is a new idea: provide a means for some people to move around a town without a map. When I am in Paris, I invariably get to give directions to people with maps in their hands. What is further dumbfounding is that they ask for information while next to one of these big district (arrondissement) maps. Obviously a map or two is not enough. There has to be a solution that does not cost more than $10 that could accomodate this need. A PDA is obviously too expensive, a service on one's cell phone could do the trick (since it already knows one's position) ?
