According to this article on Wikipedia:
http://en.wikipedia.org/wiki/Light-on-dark_color_scheme "There seems to be a dispute among vision and perception researchers about whether it is actually easier or healthier to read text on dark or light background; there is a similar dispute between users, when using each other's computer terminals."
So yeah, different feel for different people, I guess. I also don't know if the monitor type has anything to do with this (mine is the old, non-LCD monitor, what is the term of it actually... And it is my workstation in the office, so it's not like I have any choice with what I get. At home I use laptop/notebook, so for that I do have a choice :-) )
