Breakfast burrito: potato or no potato?

This comes up every time it gets mentioned in another thread so it may as well have its own. Potato camp says it soaks up the egg and makes the thing substantial enough to count as breakfast. No potato camp says it's padding and you should be tasting egg, cheese, salsa and meat instead.

There's also a third group that only accepts potato if it's actually crisped rather than steamed in the pile, which I suspect is where most of the real disagreement is hiding.

Where do you land, and does it change if it's a hangover order?
