Looks like Sony firmly believes in color-therapy, why else would they come out with two new USB mice in geeky hue? While the SMU-C3 comes with a wide scroll wheel that integrates wire storage for portability and is compatible with Vista, the SMU-M10; a slim and compact mouse comes with a groove to wrap the USB cable.
The SMU-C3 is out in pink, green, white and black, the SMU-M10 is out in blue, black and white.
Both the Sony SMU-C3 and SMU-M10 Optical Mouse are available in Europe, but the prices are not known.
