Depends on the environment. On my MBAir, if I’m in the living room, then it’s usually at 8 or 9 out of 16, if the lights or on or it’s day and I have the blinds open. Once in a while I can’t sleep, come downstairs in the middle of the night, and do something on the MBAir. with the lights off, screen at 1 out of 16, and keyboard backlight on (it’s usually off). If I’m on the back porch during the day, though, it’s gotta be 16/16.
