The Matias Wired Aluminum Keyboard for Mac is for people who miss Apple's wired USB keyboard. Many people still like the reliability of a traditional USB 2.0 connection, with a two port USB 2.0 hub, numeric keypad, and classic aluminum frame and white keycaps. This keyboard by Matias is just as beautiful as the Apple one was, and has all the special Mac functionality you expect on the function keys.
The keyboard has one special function that improves upon the original Apple keyboard. There is a volume control dial on the top edge of the keyboard that gives you more precision in controlling volume than using the keys; however, if you are a traditionalist, you can still control volume with keys on the Matias keyboard, just like the Apple one.
