Carbon fiber has, without doubt, got to be one of the most exotic materials you can choose to build things out of: race cars, road bikes and, umm, laptops? It seems that the Dell XPS 13 has started a trend because now Gigabyte is hot on its heels with an all-carbon fiber notebook which is, as you'd expect, insanely light.
This is the Gigabyte X11. As you may have guessed it features a 1366 x 768 resolution 11.6-inch screen, which is packed into a frame that tapers from 0.65-inches to 0.19-inches thick and is made exclusively from carbon fiber. Expect the hinge: that's aluminum. Most importantly, it weighs just 2.1 pounds. Or 34.4 ounces. That's 4 ounces less than the equivalent MacBook Air.
Inside, the spec list reads like any other ultrabook: a choice of Ivy Bridge processor, 4GB of DDR3 RAM, a 128GB SSD, USB 2.0 and 3.0 ports, mini DisplayPort, 1.3 megapixel webcam, blah blah, yawn yawn. Oh, and it's made from carbon fiber.
Currently there's no availability date announced, but we do know that prices will range from $999 to $1299, and for now it will come with Windows 7 Home Premium. Did I mention it was made from carbon fiber? [Engadget]
