I am looking for a lock and cable fo my MBP. I saw one the other day from a company I ha never heard of but they claim that their lock is designed from the ground up for Macs. It wasn't made by Targus or Kensignton. You'd put the lock on and then turn the back end of it to get it tight and the lock the sucker once it was in place. Looked good but now it's sold and I can't remember the manufacturer. It was $39 instead of $29 like the other guys.
