Dark themes work are only comfortable for me when the ambient lighting in the room is dim/dark because otherwise, as Alan says, if the room is bright, then the transition between the screen and the room hurts a little bit. I think the other question is in terms of readability: I've always found light background/dark text to be more readable. Maybe it's because the "brighter" nature of a light background means my eyes squint more and focus better on the words? At least with a dark background, my eyes feel more relaxed but they kind of just wander around and I can't focus on the text as naturally. Then again, I've found dark backgrounds to work really well when there's a lot of visual elements in the design of the page (i.e. not words to read but graphics to look at). (Not a professional designer, I just occasionally design things for people and wonder these things -- would love input from someone more knowledgeable).
