Apple May Turn to Carbon Fiber for MacBook Air

As if Apple’s MacBook Air needed to get any lighter, Apple is now saying that they might add carbon fiber reinforced plastic in the future, making it weigh less than 3 pounds. Not that I don’t like the MacBook Air, I would totally get one if it had the power of my Dell, but does it really need to get lighter, and if so, how much lighter can the laptop actually get before sacraficing on the technological side of things?
