Yes the demo shows voice controll works, but I could do the same thing with a stylus or touch screen at 1/4 the time and it would feel a whole lot more natural and less akward. voice recongnition for dictation is barely worth it still, after one decade of pushing the limits. I may have no choice but to use voice controll for a service call where I get prompted for a response, there is no way I would buy a voice controlled device as seen in that demo.
