I like my boards (please don't read that as "broads") the same way I like my coffee: black. That is, I prefer blackboards to whiteboards. I don't know for sure, but I reckon I'd rather have some chalk dust in my lungs that those nasty polymers used for dry erase makers.
My new office at the university appears to be one of the few that has not been upgraded from a blackboard to a whiteboard. They can do it when they pry the Crayola anti-dust chalk from my cold, dead fingers.
