Loving my new mac from pc but I have to say the mouse movement is less accurate/responsive than my windows machines.I have changed the settings in preferences with speed etc but I feel as though Im moving the mouse and the curser is slightly delayed. I felt this in the mac store but couldnt be sure until I got it home. I tried the windows mouse on the mac but still the same, is there any other mac mice I can try or any other settings? Thanks Sam
