Some laptops are thin. Some laptops last for hours. The new LG Gram Laptop does both. Available in 13.3-, 14- and 15.6-inch versions, it lasts for up to 22.5 hours per charge while weighing as little as 965 grams — or just over two pounds. Its body is built to military standards from a nanocarbon magnesium alloy, and also offers DTS Headphone X support, Thunderbolt 3-capable USB C ports, and booting times under 10 seconds.
