MacBook Air (again)

Another interesting thing, the MacBook Air has no Kensington lock slot on it. In theory that means its much more susceptible to theft given its size and appeal. The company I work for has a policy that all unattended notebooks must be secured. As I was pondering/googling that, I ran into a couple of amusing videos showing the hacking of the lock with a roll of toilet paper. I love it. Evidently after this round of videos/posts Kensington made the locks marginally more secure although there still seems to be plenty of evidence that the locks only deter casual theft.

So what is the real value of that slot and does anyone use it?

At work I have 2 laptops, both secured to my desk with these kind of locks (yes, i'm going in armed with a toilet paper roll tomorrow). At home my backup drive is secured to my desk with a lock like that. My big MacPro isnt. So they'll get the expensive machine with my encrypted data but not the backup drive (which also has encrypted data) unless they're determined. And they have to get through the ADT alarm system and 4 dogs. I think thats good enough.

Did I mention I periodically backup my really important stuff to DVD and place them in my fireproof safe (which is in the basement and weighs 800lbs)? 

Ok so i'm a nut, but my data is important to me. Is yours important to you?
