    The S440 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 convenience and style. Black ports and a sandblast finish top off the design embellishments on the S440, which is available in both Silver and Gunmetal.

    light weight
    mouse pad may be the worst design I have ever seen for a mouse pad. The touch click is none responsive and the right click is a complete mystery. The pressing on the mouse pad is extremely loud and annoying. I will be replacing the system with an alternative vendor system as the mouse pad is in all your new systems. VERY BAD DESIGN
