Apple to Adopt Carbon Fiber for Lighter MacBook Air?
Apple enthusiastically claimed ownership to the world's thinnest notebook earlier this year with the introduction of the MacBook Air, but is rumored to be unsatisfied with the system's weight, which it now hopes to drop below 3 pounds.Carbon fiber is described as an extremely lightweight material that is exceptionally strong.
Apple is expected to keep the upper aluminum chasis of the MacBook Air, but may replace the bottom cover with one constructed from carbon fiber. This could trim the notebooks weight from slightly over 3 pounds to 2.78 pounds.
The rumor site believes the shift could happen as early as next year.
