Well maybe things have changed IMMENSELY since I graduated 2.5 years ago but I never saw a single person use a kensington lock, not people living in dorms not people in the lab, no where (and yes, "back then" they had them, my laptop has one). It really just seems like an excuse to be haphazard with your laptop. Don't leave it anywhere, locked or not. Just because you locked it doesn't mean it's even REMOTELY safe. Oh great, so no one will steal it. What about some guy who trips and knocks it off the table or some other idiot who accidentally spill soda or something on it. I'm just saying there are SOOOO many things that can go wrong with leaving your laptop somewhere unsafe that even if it's locked you still shouldn't leave it. If you're in the dorm room put it in your locked cabinet when you go to the restroom, or, heaven forbid, room with someone you trust to keep an eye out and not let some stranger come in yank your laptop. It's really not that hard to prevent, just use your brain and don't be lazy.
