2FastCPU plays with the Macally iceMouseJr Is it good? They'll tell you here.
With the iceMouseJr just being released, we figured it would incorporate
a new optical eye for faster tracking speeds. Again, we were let down, as Macally
has apparently not changed anything internal to the mouse. To be direct, this
optical mouse, as with most others, suffers from being easily confused. Quick
movements across the screen or in a game cause the cursor to go berserk. That
effect is easily minimized by jacking-up the acceleration.
