The US Transportation Security Administration, or TSA, has officially stated that travelers passing through US airport security with the 11.6-inch MacBook Air will not have to remove the little laptop from their bags for inspection. Unfortunately, that's not the case with the 13-inch model.
Size is the differentiating factor. According to the TSA blog, any electronic device considered to be of a "standard laptop" size or larger must go through the x-ray machine solo. Apparently, the cutoff point is at or very near thirteen inches. The iPad, Kindle, Nook and other small devices, including the entry-level MacBook Air, may remain stowed away during screening.
As if travelers needed another reason to lust after the thing.
