Gunmetal MacBook spotted in Cupertino

Word on the street has it that a new “dark grey” or “gunmetal” colored notebook has already started to make its rounds at Apple’s campus, specifically at the area where stress tests are usually conducted. This source claims that the new MacBook is noticeably thinner compared to current 13″ models, although everything else looks the same (other than its metallic sheen, of course). One thing’s for sure – the whole world will once again drool over the release of this mystery MacBook come Macworld Expo early next year.
