Now isn’t this interesting – have you ever used a mouse that wasn’t a handheld? That’s what we thought, too, as we heard of Sigma A.P.O.’s wireless handheld mouse. Specially designed to look like and be used like a pointing device, the SGMRF3 (as it is known) will not include a gyroscope, using a standard trackball instead that will let you control your computer pointer quickly. This seems to be more of a compact mouse for presentation purposes, sporting a 400/800dpi resolution and up to 50 hours of battery life, where it will arrive in Japan next month. It seems like some sort of gaming device though if you ask us.
