GPS navigation tech is now small enough to fit into a key fob, resulting in this little trinket that can help those of us who are profoundly absent-minded. Mark your spot after you park your car in a giant parking lot, and when you return, this intelligent digital compass will lead you right back to your vehicle.
Sure beats putting a ping-pong ball on the old antenna, like we used to do back in the old days. This kind of convenience is not cheap, though — the IDC Ecco Intelligent Digital Compass Personal Pocket GPS Locator will set you back $90, available later this month. Now all we have to do is hope the GPS satellite network keeps working.
