The “Matias Wired Aluminum Keyboard for Mac – Space Gray” 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 and numeric keypad. This keyboard has a space gray aluminum frame and black keycaps. This keyboard by Matias 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.
