Friends, have an upcoming trip to Asia and would like a security cable for my computer. I have a MBA 13" 2010. I've seen appallingly bad reviews of the maclock product. Here is another option - pricy - from Kensington: http://blog.kensington.com/wp-conte...Dock-MacBook-Air-Security-Dock-Keyed-Lock.pdf Anyone actually had experience with these products? Anyone have a good recommendation?
