If you travel often or constantly use your MacBook in a public area, you should have some sort of security setup just to keep your precious laptop and its data safe. The most commonly-used form of security is a laptop lock or tracking device.
Hidden is a recovery app that tracks the location of your Apple computer, collects photos using the built-in iSight and takes screenshots of any activity once it is reported stolen. Hidden retails at $20 but from now until January 2011, you can get it for free. Just head over here and sign up then download the installer.
