One advantage of braille is being able to quickly count how many digits are in huge numbers. I know my display has 32 cells. Examining this number, I have one empty cell on the right, and the number sign. I instantly know there are 30 digits. Try that on a monitor! Yes, this rarely comes up, and yes, I'd still rather be able to see a real monitor. But it's one tiny thing I'm faster at than sighted people. Let me have it.
