Sorry, don't know if this is the right place to ask this, but does the Apple Store sell any "good" anti-theft security locks for the MBP/MB? I was checking out Apple's selection online, and most, if not all of the Kensington locks got absolutely terrible reviews! I reading about some saying the lock "destroyed/ruined their MBP", etc. Anyone here have any good, problem-free experiences with a lock? I'm going to college this fall with a new MBP, BTW, so parents are being rather insisting on this one. Thanks!
