i'd be mortified if someone bought me one of these for xmas. It's a product which I don't believe has had any real positive human effect on the way we live. it's a true gadget, a quick fix of personal security, sure it means that a satellite guides you to your destination, but it removes the need to understand maps, geography, landscape, how places connect together - all good things to know; effectively it removes the need to think. Was everybody really lost before the sat nav arrived? i'm interested in the possibilities that mobile and GPS mapping solutions will offer, especially the more social elements, the ability to publish and share personal points of interest, places, moments and that. but getting from a to b? i guess i'm a tad old fashioned in that sense.
