When I tested the Wii out, it wasn't much different than using a laser pointer. When I host meetings at our planetarium it takes *a lot* of practice to precisely point to celestial bodies and other astronomical phenomena. After just a few hours of practice it's not very hard at all. Your body just needs to learn how to use those stabilizing muscles/tendons needed to guide the Wiimote/Nunchuck. After just a few weeks of play time, I'm certain all of us will be great at it.
