serves its purpose, very useful for the sustained use of pointing device. Personally, I find it necessary to use a Magic Trackpad, which brings long to keep fingers slightly raised to avoid touching the surface inadvertently. The wrist rest wrist falls and makes the natural standby position. One downside: it is very fragile, and can easily be punctured by a blunt object (for example, dropping a pen above). It's serviceable but with unsightly tape.
