If you are spending a significant portion of your work day staring at a code editor, surely optimising it somewhat is worth it. I only code a little in my free time, but have a dark background makes it easier to stare at the screen, and having, say, variables a particular colour makes them stand out when scanning through code. It's like a professional cook having all his kitchen utensils laid out in a particular manner that's efficient for his work routine. I'm sure there's plenty other analogies from different professions you could apply.
