GPS service can be a wonderful thing, but one of its downsides is waiting for GPS-enabled devices to get their fixes: it’s not unusual to wait two, three, or four minutes for a GPS device to figure out where it is—and that, of course, is assuming the device can pull in enough satellite signals to get its position at all. This delay is widely seen as an impediment to many location-based mobile services, since consumers don’t often have the patience to wait around for location and mapping information.
