Obviously the Air does not include any attached locking features. So, I'm looking for some sort of external lock: - either a case that can lock up and be kenzington locked to something or - a lock designed to sort-of wrap around in a + shape around the Macbook in order to keep it safe. Does anyone have or know of any useful solutions for locking an Air up? I'm going on vacation... needless to say, I don't exactly have full trust in the part-time workers who do the cleaning daily in the various rooms at the beach-side motel. 11.6-inch Air.
