If you have a laser mouse you may need a pad with a flat, even surface that reflects the light properly. Special mouse pads are available. If you have a cheap optical mouse like I do, it will work on a natural wood desktop but it is not nearly as precise as a good laser on a flat, uniform surface.
Logitech says that mouse is optical and should work on a wide range of surfaces. It shouldnt need a special mouse pad, just a uniform surface.http://www.logitech.com/index.cfm/349/6315&cl=hk,en?WT.ac=ps|6276
