A friend of mine asked how the auto-brightness feature on the iMac could work without using the camera or turning on the LED? There may be some reason (like a separate illumination sensor near the camera but not part of it) but I don't have the answer. I admit it has been bothering me a bit. It is time someone offered an attractive lens cover for the iMac but that will stop the auto-brightness working as well.
