Apple unveiled a new MacBook Pro that replaces the function row on the keyboard with a touch screen. The new mini Retina display will change functions depending on the app you’re using. It looks like the general function keys will still be there around the customizable area. In the top-left corner, you’ll see a touch button replacing the Escape, key for instance. At the very right, there will be a Siri button, the two volume buttons and a single brightness button that probably triggers another menu.
