on the laptop there this square thing that can be use as mouse, are there usb thing similar to that thing i can use on the pc. i want one of them if there because the mouse making sound i want a quiet mouse. if there no such thing then are there mouse wouldnt make sound when clicking it.

Interesting idea!
