well my mom got a new wireless optical mouse. it is a micros innovation mouse...she got it for $40. it came with a cradle, rechargeable batteries, and a installation guide as good as a colorwheel for the blind. it took me 3 hours to get it to work but i finally got it ^^ the cradle recharges the mouse when not in use, like those ibm bluetooth mice going for $120. i understand where wires would be bothersome, but i like my ibm optical mouse with its blue led wheel. it shines BLUE! ^^ my mom hasnt had any problems with its refresh rate but then again she isnt a gamer, she is just an old lady.
