I was looking to buy a new mighty mouse on ebay and I wondered. Is there an explanation how people are able to sell a mouse they advertise as brand new for prices as low as £3? Btw, apple must do something about the trackball issue. By any reasonable standards a mouse cannot go out of action in less than a year (because the trackball is blocked). I admit I am a victim of my addiction to the MM, so the least I can do about it is look for other places to buy, and not apple.
