I love flying with the shade up. But if it's a long haul flight and people want to get acclimated to the new time zone I feel too guilty leaving it up. Hate the trend of having to have the shades down. United flight attendants waste no time telling me to put my shade down. I think the flight attendants like it because everyone falls asleep, or acts like it's nighttime and leaves them alone.
On a day flight to Europe we were flying over gorgeous ice floes over Canada and Greenland. It was truly spectacular scenery. I was the only one looking out the window. Everyone else was watching movies or sleeping with their shades down.
