I see GPS as the third major player in the triumvirate of mobile technology. First, we put in place a ubiquitous network connection. Second came the cameras, so we could record what we saw. Finally, the GPS chips, so we can track where we've been. Beyond mobile phones, now laptops and tablets are coming with GPS built in, as well as point and shoot cameras, cars and a wide range of other devices. On anything that moves, you could imagine adding GPS.
Location is a subversive technology, at once willfully tracking our moves and broadcasting our position. With a camera, GPS becomes corroborative evidence. In a car, GPS is an escape route.
It's also very, very creepy.
