For a Stolen cell phone or a laptop. http://preyproject.com/ Just download the software register your device. If it gets stolen you can track the shifty little bastard that stole it, find his logs on Facebook, email etc... THEN call the cops and let them know you have their asses tracked with your stolen property, with logs etc, AND you can even take a picture of the fucker with your laptops webcam while they are using your shit. OR you can just go all Mission Impossible on them and completely lock the machine down so no dumbass can use it again.
