Traveling in Turkey for five weeks, suffering with TomTom putting street names on cities in zoom out mode (just try to navigate when all the cities have names like Ulugol Mevkii and Indinkivi Mevkii! I mean hey, TomTom, what are you thinking?), when I discovered Pocket Earth. Now were talking Turkey. Not only great off line maps but easy to use pin drops, routes (just cant change them without net access), speed, heading, map scale. I think it was three bucks for all of planet Earth!
TomTom was good for pre-trip planning to help figure out drive times between locations, and helpful in large-ish cities, but was a disappointment overall.
Overpriced by an order of magnitude.
