The A4Tech Optical mouse is an interesting mouse because it does not require batteries. It is also wireless which is what makes this mouse interesting. Instead of using batteries it is powered by electromagnetic induction which charges from the mouse pad. The mouse pad gets it’s power from the USB connection of your PC and then transmits this power to the mouse to keep it running. I think this is a great idea. Cordless mice batteries do last quite a while, but when they die you tend to not be prepared and have to dash to the shops quickly.
It has a resolution of 800dpi and and might not make it to this side of the world. It is priced at $21 over in Korea.
