Actually, I find a darker system to be harsher on the eyes particularly if text becomes hard to read. Things like dark text on a dark background require much more effort to focus on.

A light background and dark text is just the most natural way to read text, it requires the least amount of focus.

But yes certainly different people have different preferences - that's why I want to have a couple of choices for the UI theme in the future. In MoI v3 moving to have more of the UI being based off of parameters instead of images should help with that.
