Pfft. Your puny eyes that are not accustomed to white-on-black are, um, puny.
But seriously, I like the white on black style. I've used it myself since grade 11 when me and my friends had a colour theme day in drafting by screwing around with the windows schemes. I don't know how, but it'd be nice to be able to choose the colour scheme... Or maybe add a new one instead of replacing the old one.
