Design Concept of the MacBook Air

This is based on my first reaction upon seeing that design, ie this is my personal opinion. For those of you unfamiliar, ohaguro was a tradition in Japan a long time ago for women, kind of like make-up. Fyi just to make it clear, I've never seen it personally but sounds... interesting looking. In a modern context it can just mean gross teeth after eating something black, like calamari ink.
