It's apparent from first glance that the Sabertooth is intended as such, given the six extra (programmable) buttons found on the shoulders and back of the controller, and the tiny OLED screen found along the bottom (allowing for the programming of said buttons).
Simply put, the model is the data (and by extension the HTML content of a website or app), the view is what you see on the screen (defined by the CSS styles of the user interface) and the controller is the logic that ties the two together (often expressed as the JavaScript or other interactive programming).
