Actually iPhone, Android based touch screen phones and even iPad only recognizes 2 fingers on the screen at a time but 3M is testing the monitor for 20 fingers response within 6 millisecond time.
In this picture, you can see couple of users are moving pictures on screen with their fingers. And ion the second pictures, they are playing on MS Paint. As you know, Windows 7 and Ubuntu are having Multi-Touch drivers, so using those OS on such monitor will not be much difficult.
