I'd like to get a lock or locks for my future mac pro and Cinema Display purchase. Yes I hope no one breaks in, but if they do, I want to make it next to impossible to get away with something so important. I'd need them to be long enough and be compatible with the lock holes on the hardware. The Apple Store appears to only sell a few Kensington MicroSaver Locks meant for portables. Are these good? Is there another model or brand to look for?
