I think what Kheldron is refering to is the sound the mouse makes by itself, even when not hooked to a computer (the microswitch or whatever (I am for not tech savvy) making the sound). Even the keyboard feels like it makes an awful lot of noise when rest of the house is silent and everybody else are sleeping.

Laptops with their soft keyboards and mousepads are the solution then, even though fan of my laptop is way more noisier than on the tabletop; it's actually a lose-lose situation, but people playing blood nations in Dominions got shortest straw when trying to stay as silent as possible...
