One: Kindles aren't in color - yet. B & W is a huge limitation for map purposes! Winner: handheld GPS preloaded with local-level maps. Two: reading glasses. Kindles do have a screen size that allows somewhat easier reading by those of us who use reading glasses regularly. Most GPS displays are very challenging to use without slipping on the readers (although I did find sunglasses with bifocal reading lenses built-in, at a local truckstop), so even a B & W display could be handy. Winner if fumbling with glasses is impractical: Kindle. Three: I love paper maps and always carry a selection, but they really do take two hands to manage. It can be tricky to do while stopped at roadside or a stoplight, and again the scale can be a problem because it's unchangeable. The Kindle has six font sizes available, but I wonder if this will translate to six useful zoom levels on maps. If it does, the winner could be Kindle here too. But I'll never totally give up paper maps unless they make color displays that are large enough for the presbyopic crowd.
