Genius announced a new wireless mouse that uses a gold-capacitor instead of a batter to hold an electrical charge.
For about $40, you get an otherwise common mouse that works via a 2.4 GHz connection and a distance of up to 45 feet between the sender and receiver. The manufacturer says that the DX-Eco works on surfaces such as dusted glass, marble, carpet, sofa, delivers a resolution of 800 or 1600 dpi and integrates seven buttons. The mouse works with Windows XP/Vista/7 as well as Mac OS X 10.4 and higher.
Genius says that the gold-capacitor can be recharged up to 100,000 times.
