Took my Graham to Las Vegas went through without problem in my laptop bag. Left from DIA to LAS went through x-ray machines in each airport without problems... the two laptops, two DSLR cameras, external drives, several CF cards, 5 canon battery backs, plus three in the cameras, and my ipod all made it through without a problem. Just I took up a bunch of those silly plastic bins. one for the shoes, one for each laptop, cameras in one, laptop bag in one...
