Engadget - Well hello there again, Gigabyte X11. Hot on the heels of yesterday's leak, Gigabyte's just made its 11.6-inch X11 laptop (or is that an Ultrabook?) official. At 975g (34.4oz) it claims the title of "lightest notebook on earth" -- and weighs even less on Mars. Design-wise, you're looking at a 16.5mm (0.65-inch) to 3mm (0.19-inch) thin Macbook Air-like body made of real carbon fiber (!) with an aluminum hinge. Under the hood you'll find unspecified third generation Intel Core processors (read Ivy Bridge), 4GB of DDR3 RAM, Mobile Intel HM77 Express chipset with Intel HD Graphics 4000, a 128GB SSD, WiFi b/g/n and Bluetooth 4.0.
