Sony goes for high style with its SMU-WM10 wireless mouse, forgetting that objects that are manipulated by human hands are generally easier to use if they conform to the hand's shape. The rectangular 800dpi mouse is only 18mm thick, nice for traveling but compounding its ergonomic difficulties.

On the upside, Sony says it will last 2.5 months of 8-hour-a-day use on one battery. The SMU-WM10 is available in black, white, or red, and the transceiver is small enough to hide inside its casing.

Taking a close look at it, are the left and right mouse buttons incorporated into the case, a la Apple's Mighty Mouse? Hope not. It's $49 in Japan; you might find one on eBay if you look hard enough.
