There are locks with tighter security, but it's easier eliminating the need for the stupid lock. It's more likely that somebody will spill coffee on my computer than steal it, particularly because I don't leave it out of view. I do often leave other things unattended and have never had anything stolen. If you are using a laptop in a high-crime area, I suggest not leaving that laptop alone in this area. A lock will not stop somebody from vandalizing it.
