A note to future would-be thieves planning on stealing Apple laptops: You can use a small piece of tape to obstruct the built-in iSight camera to keep from being identified by police as the person who stole a MacBook.
See, people have found ways to remote control their MacBooks to take photos automatically with the integrated cameras. They can make copies of the photos and show them to people, like police, to help identify you.
Then the police come and arrest you. Careful out there, ruffians!
