Hi all, while I was using my new aluminum macbook, I notice something. I put my macbook beside my table lamp, so I can type and read my book at the same time. When I open my lamp (white light) beside my macbook, my macbook's screen becomes brighter After the Delay of 2 seconds, and when I turn my lamp off, it becomes dimmer, same thing it takes around 2 seconds to get dimmer. It's like it takes time to reflect the light from the lamp to the screen. I guess one of the new feature I can think of is, you can change your macbook's brightness dimmer, and save more battery power this way. has anyone notice this effect?
