The sun shine directly through the Apple logo on the back side of my laptop, creating a yellowish shine through my window. Hey, wouldn't it be cool to have the whole back of the laptop transparent (like in the Apple logo)? That way you can turn off the brightness of your screen and save battery life while still be able to see what is displayed. To test it out yourself, requirements: - One sunny, bright day - One MacBook (Pro/Air) Hold your MacBook directly towards the sun. You see the yellow spot more easily if you turn off your brightness. If you don't have a sunny day, just hold it close to a bright shining lamp. (With the Apple logo the nearest to the lamp.) Your comment please.
