According to a group of Germans — a people who know a thing or two about the subject — the edge of a MacBook Air, quickly drawn across the softly pulsing skin of a human throat, is enough to slice through windpipes, sever sinew and squirt spouts of crimson-scented gore. It's also sharp enough to slice a loaf of bread or accidentally dice an elbow. Apple currently has no plans to adopt either MBA "feature" into a hip, upbeat television advertisement, backed by the melodious lyrics of Yael Naïm. Pity.
Update: Sadly, it appears the cut was actually from a regular Macbook, not an Air. I'm pretty sure that means the Air is even more dangerous! – Joel
