Microsoft has unveiled the Surface Pro 3, featuring a larger 12-inch screen with a 3:2 aspect ratio and a resolution of 2160 x 1440. While it's bigger than its predecessor, it's thinner (measuring 9mm) and lighter, weighing in at 800g (making it significantly lighter than the Macbook Air). It's faster as well, packing up to an Intel Core i7 (making it the thinnest ever gadget with an Intel Core i7 processor), and fully adjustable, featuring a new kickstand on the back that allows the screen to lay back at a near-flat angle of 150 degrees. The Surface Pro 3 starts at $799 with a Core i3 processor, and storage capacities ranging 64GB to 512GB. Go here to pre-order yours.
