Quick Tech question about the Wii-mote and the nunchuck

Note... i dont have a Wii.

First off....Excatly how much movement can the gyroscopic sensor in the Wii-mote.....sense? Full articulation of an arm and wrist or is it more limited than that?

Second.....Is the sensor in the nunchuck attachment ....the exact same as the one in the Wii-mote?

The remote can sense tilt and motion in any direction.  The nunchuck doesn't seem to be as sensitive as the remote, but it's hard to tell since I don't have any way to measure that quanatatively.

The remote doesn't have a gyroscope in it.  It has computer chips that detect motion and measure tilt.  The tilt sensing is very accurate, the motion sensing seems a little less accurate, but I can't tell whether that's because of hardware limitation or software.

thanks guys..
