Apple made a concerted effort today to highlight the reduced impact its new products have on the environment.
This effort all started with Steve Jobs' open letter in 2007, A Greener Apple, announcing a long-term plan to "protect the environment and make our business more sustainable." The letter was released partly in response to a Greenpeace campaign, encouraging Apple to reduce the amount of toxic chemicals in its products and improve its recycling programs.
Today, the star of the show was Apple's new "unibody," a single, complex chassis for new MacBook and MacBook Pro units fabricated from a single brick of aluminum. In a video posted on its website, Apple noted that as a result of the new fabrication process, fewer parts in the laptop means a reduction in weight, size, and the amount of other material necessary to hold the device together.
