10/GUI showed already 2009 how multitouch can be brought to laptop / desktop. Without stretch out the neck, the arm and without blocking the display with your hand. Apple / Microsoft / Google should see the demo and consider to implement it. Only one concern: 10/GUI is not pixel precise like a computer mouse. The bigger the display the less accurate the 10/GUI control, except you use a bigger touch mat, matching the bigger display.
