Here s a tiny GPS receiver from i-Blue that communicates with your Bluetooth-equipped laptop or PDA and it's pretty smart, too. Even though it has a battery that will operate the unit for 30 hours per charge, it's polite enough to turn itself off when it's too far away for Bluetooth reception. Just put this 2.7-inch tall i-Blue PS-3200 on the windshield of your car and it ll see those sat-birds hovering over the earth. Whenever a Bluetooth-enabled device is nearby, it greets it with a fine how-do-you-do and helps you find your way home. The battery can hold out for 48 hours on standby before quitting. Best of all, the thing costs just $105.
