It would have to predict the model numbers of the planes though: some newer ones I have been to (A350s) seem to have automagic dimming windows. Getting on flights with such windows is better even if you have to sit in the sun!
On the other hand though I detest window seat passengers who insist on having the windows closed for take-off and landing. I'd like to know when to expect a thud, thanks. The electric shades are nice in that aspect because they are never fully opaque.
They're more concerned that my seat back is not pushed back by the 3mm that they move.
I don't travel enough on other airlines to make generalisations.
