technology

Technology that interests me this week is GPS (Global Positioning System). My husband tries to explain there are satelites in space that use a triangulation formula to exactly pinpoint your location here on earth. The amazing thing to me is the feature where you may also obtain specific directions to another location by using this device. Map Quest is very useful, but this is even better!! My concern with all technology today is the cost. How much will we spend for faster, more convenient, and immediate connection to information through mobile devices?
