I am pondering the automatic keyboard lighting of the Apple iPad Magic Keyboard, which is based on ambient lighting and seems to be similar to the lighting adjustment on phones and tablets. Right now I am using the keyboard in a very well lit room and therefore I don’t need the keyboard on maximum brightness, but it is and that seems to align to phone screen brightness. You want phone screen brightness to increase outdoors so that you can read the screen, but it seems to me the backlighting of a physical keyboard should be the exact opposite, near zero in bright light, to save battery, and increase in brightness in darker rooms.
