Carbon fiber is lighter and it's durability is comparable to aluminum. A thinner and lighter MBA may be achieved with the use of carbon fiber without sacrificing durability. In fact, it's used in other technical industries such as race cars and airplanes construction. Other laptop companies have already implemented it into their design, including Lenovo's X1 Carbon and Sony Vaio Pro 13. With that said, would you guys like to see thinner and lighter MBA's be made out of carbon fiber in place of the silver aluminum body we are all accustomed to?
