The "Matias Wired Aluminum Tenkeyless Keyboard for PC - Black" is for people who don't want a number pad, but still want the beauty of a slim aluminum keyboard, with the reliability of a traditional USB 2.0 connection, with a two port USB 2.0 hub, black aluminum frame and black keycaps. The keyboard has a volume control dial on the top edge of the keyboard that gives you more precision in controlling volume than using the keys.
