I purchased the MacMice Two button BT mouse to replace my Apple one button BT mouse. I used it for about a half day and could not stand it any longer. So I put it back in it's box amd went back to my Apple BT mouse. The resolution is much better as well as having no perceptible delay in normal use.wPod said:I use The Mouse BT by MacMice and it is usually OK durring games. . . until the action gets really intense or you need really fast, really percise movement. then you notice a lag and you get your ass kicked. Im assuming its about that way for any BT mouse simpley because of the lag that is associated with any BT use.
