I really like my iPad, and the thing is pretty lightweight already with its aluminum chassis and coverings. Future iPads may get even more lightweight thanks to a patent app that has surfaced showing Apple is looking to carbon fiber.
Lots of ultraportable notebooks on the market have carbon fiber in their construction, so this isn’t that far out in the least. The patent outlines a new outer shell for the tablet that uses “layered fiber in matrix type material.”
I think it would be epic if Apple took the iPad, made it in carbon fiber, and then left the fiber exposed for all to see. I would hope they use the cool looking carbon fiber, not the flat and ugly looking dry carbon fiber. Carbon fiber can break in some uses so Apple would apparently use a frame made from CF to strengthen the works.
