I'm probably in the minority here but I don't normally sit around in the dark at 11:00 in the morning whether I'm at home, at work or in an airplane. For me as a geologist, one of the great pleasures in flying is observing land forms and weather related phenomena.
So I'm that guy at the window seat with the shade open during daylight hours. I do try to be considerate and lower the shade half way if it is obviously interfering. But I'll take a brilliant lightning storm over the Pacfic, a sunlit Grand Canyon or the splendor of a sunrise over the snow covered Alps (and I've seen them all) any day over I Love Raymond reruns.
