Agree on that. I go for the aisle myself but I consider the window shade position to be the prerogative of the person sitting in the window seat. The only two situations that I consider annoying are if someone is constantly moving the shade up and down when it is very bright outside, and during flights around dawn when the person at the window doesn't notice that the sun is glaring right into someone's eyes. Other than that I could care less, and think the default position should be open so people can look out (though I don't mind if the person on the window chooses to put it down). If somebody wants to sleep they can put on an eye mask, just like if somebody is cold they can put on a blanket. Looking out the window, even just at clouds, is a joy of flying.
