Clammy Modding
japala writes "Some people tend to have cold hands while they type the keyboard or use the mouse. Equally as many suffer from sweaty palms and that feels really annoying while using the mouse. MetkuMods have made couple of tutorials in true DIY spirit that will try to make your life easier. These devices may have started as a joke but trust me, they do work. See the MouseFan and BreezePad."
Well that's the same thing I do, except you have your palm suspended over the mouse(and it doesn't get sweaty that way I suppose) whereas my palm is touching. It's the same amount of wrist movement whether your palm is touching the mouse or whether only your fingers are, for me anyway. I rest my entire palm on the mouse and still only move my wrist around. The original poster said something about using "just [his] fingers so that only [his] wrist has to move around rather than [his] entire arm" As far as I can tell, it would be the same kind of movement, just your palm wouldn't get sweaty. I don't see why resting your palm on the mouse would preclude use of your wrist and force you to move your arm. Maybe I'm just strange and/or dense.
