Well done, continually updated and expanded upon, a developer in touch with forum suggestions, and the whole thing's donation-driven. Doesn't get any better than that.

For someone like myself who uses my Mac in places that it is unlikely to get stolen (I go to a very small college), it beats lock-and-key and gives me profound peace of mind when I walk away to use the restroom or chat with other library denizens. Perfect tool. (Oh, and if you don't like the 'armed' noise, you could always just remove it from the Resources folder, right? ;)
