Voice is going to be much slower and less accurate than a mouse. Its fine when there are only a few objects to control, with lots of independence such as other players in a shooter.
But something like SE? Or even just a windows desktop?

IMO, it would be better to have something like a touch sensitive screen, with a button on your thumb. That way you can reach over, and pinch the air to click and drag as if you were picking something up and dropping it somewhere.
Using two hands would make for an obvious way to stretch a window for example.

Still low on the precision, but at least it would be quick and easy to use. And it would be really useful if we ever get hologram type 3D.
