Except with the PS eye/wand you don't have to actually aim at the invisible mouse pad just like you don't have to aim your mouse at the pad. With the wii-mote you are aiming with the camera while PS eye is stationary.
Even the wii-mote isn't ideal for fighting games yet it's does ok.
P.S I think some is too quick to dismiss motion controls not realize as in my example of Sony's wand that they could benefit even PC gamers.
