Thinking about recovering your laptop in case of theft? Undercover from Orbicule (we've mentioned it before once or twice) sports a nice additional "feature" in terms of a money-back guarantee. If your Mac is reported stolen Undercover will monitor and report IP addresses that should narrow down the search, as well as take both screenshots and iSight snapshots at regular intervals and send them back.
Finally, it will mimic a hardware problem presumably prompting the thief to take it in for repair or sell it, in which case it will display a message indicating that the computer has been stolen, etc. Orbicule is apparently so confident that Undercover will allow you to recover your machine that they're offering a money-back guarantee for the cost of the software if you do not. They have an interesting account of the recovery process in an actual case.
Undercover is $49 ($39 for students; education site licenses are available).
