The new Apple laptop that your geeky officemate is swooning over is “the greenest MacBook ever,” according to the company. (But remember, kids: Hanging on to your current laptop is even greener.) Instead of being cobbled together from various pieces, the new MacBook’s main frame is cut out of a single piece of aluminum, and the discarded metal is recycled. It arrives to stores in 41 percent less packaging than the previous generation, and can be returned to Apple for recycling at the end of its life. Like other Apple offerings, the newbie boasts arsenic-free glass, is backlit with energy-efficient LEDs, and contains no mercury, brominated flame retardants, or PVC. The new MacBook won a Gold rating from the Electronic Product Environmental Assessment Tool — and if you set as your landing page, all the better.
