AT&T Sells Tiny GPS Tracker with Mobile Alert Service

If you find yourself losing things—keys, children, pets—on a regular basis, it may be time to step into the technological age with this little 1.7-ounce, water-resistant Garmin GPS tracker. It packs a tiny AT&T connection that you can configure to send out e-mails or text messages when it crosses over the invisible geofence that you've set up for it.
Even without it breaching the parameter of your hoity-toity geofence, you can use a standard web browser or compatible smart phone to track the device's location, though you're only able to see its last 10 known or requested positions unless you pony up $5 a month for premium tracking. Other than that, standard tracking is free for a year.

The Garmin GTU 10 runs $200 with no contract or setup fees required.
