One even low-priced Garmin GPS says that Foursquare is a location based social network and the gps thing includes preloaded 4square points of interest.

says "Foursquare Places offers 120+ points of interest across 200+ countries and territories"
120 poi caross 200 countries?? Isn't that fewer than 1 per country? Is that a reason to buy it?
