If we take the word of Citigroup analyst Richard Gardner, the much rumored new aluminum MacBooks are already winging their way from China to Apple's secret underground storage facility. This fits with speculation that we'll see a notebook refresh from Apple some time in October.
Gardner's "field checks" (read: crystal ball) have told him that the new MacBooks will have a “very thin aluminum casing, an LED-backlit display and an aggressive entry-level price point."
Aluminum makes sense. Everything else in the lineup is turning into aluminum (except the iPhone's rear case). LED backlighting also makes sense. And the "aggressive entry-level price point," combined with the iPod price drops, could be the mysterious "product transition" we keep hearing about.
Other parts of the internet will surely cry "fake," saying that new MacBooks would have been released for the back-to-school season. We say no. What better way to clear old inventory than to sell it off to the kids?
