The advantage of a Locator over something like

Manipulate[
  Graphics[Point[{x, y}], PlotRange -> 1],
  {x, -1, 1}, {y, -1, 1}]

is that it can be directly moved with the mouse.  To easily move a point 
in 3D, one needs a special input device.  If you do have such a device, 
then you might want to look at the documentation page 
guide/GamepadAndDeviceInterface .  It should be possible to use it to 
move a point in 3D, but I never had the chance to try this because I do 
not have access to game pads.
