Stylish, Svelte Design. Premium Features.
The S431 shell combines aluminum and magnesium alloy for both durability and lightness. A single unified hinge adds strength, while also enabling 180-degree opening so the Ultrabook lies flat or rests at any angle. Unique attention to detail like indented sides for carrying add to the eloquent convenience. Black ports and a sandblast finish come standard.
