Unity Global Mouse Events

Question

Most Unity tutorials suggest using mouse events in the update function, for example:

function Update () {

   if (UnityEngine.Input.GetMouseButton(1)) { 

   } 

}

This seems really inefficient to me, although it seems like using onEnterFrame in AS or setInterval in JS to power the whole application - I would rather use an event-based system.

The OnMouseDown () method is useful, but it is only triggered if MouseDown is on the object, and not somewhere in the scene.

So here is the question: is there a MouseEvent in Unity to detect if the mouse button is disabled globally, or is this an upgrade solution recommended?
