Check out this entry by Blogger Bob (with video), explaining why the Macbook Air has caused problems going through the x-ray machine in airports. Watching it, I trust Bob. He seems like a straight shooter. And I'm impressed that he became aware of the problem by reading other blogs, and so quickly responded with this video. Smart.
