    im a little confused...when it gets darker the display gets darker and when it gets brighter the display gets brighter...

    this might be how they all work, it just doesn't seem to make sense to me. i understand maybe it gets brighter to combat the glare from a sunny room or something.

    That's correct.

    In a dark room it's easier to see the screen, so it dims.

    In a bright room it's difficult to see a dim screen, so it brightens.

    That's exactly right. The logic here is that when you are in a dark room the screen dims so as not to blind you. (Ever flip the light on when you have been in a dark room for awhile?)

    i suppose that's true but i think i would like to be a little brighter in a dark room especially late at night.

    If it's not on full brightness, turn it up.

    Although this isn't an ideal situation you could always manually adjust the brightness. Hmm... would be nice to be able to have a setting that remembers what brightness level you prefer for different ambient light levels.

    The idea is to prevent eye strain.

    If your in a pitch black room with your screen on full, it kills your eyes. When it's bright, the screen brightens so you can see it.

    Staring at a screen on full in a dark room is like staring at a light bulb.

    There's an ambient light sensor for the screen for all Macbooks or just the new aluminum ones?

    And every other Intel laptop model, all Intel iMacs, and the iMac G5.

    Possibly also the last of the PowerBook G4 line.

    To the OP, have you ever even put it on full brightness at night? You can and will ruin your eyes like that.

    Haven't you ever noticed that your car's instrument lights dim when you turn the headlights on?
