I have to say, with this in mind, I actually didn't mind the dirt holes in the ground that I used in the African bush.
Now, if only the bats didn't hang out in there at night!
There's something to be said for squat-a-potties, in other countries...
EDIT: Actually, I have to amend what I said. I'm remembering how much more the women on our research team were bitching about the hole in the ground than the men were. Why? The men could just aim and pee, right into the hole in the ground. There wasn't even a toilet seat to avoid spraying.
The women, however, still had to deal with a bifurcating urine stream (it goes everywhere, due to the labia and possible hair interference), holding our underwear far enough away (without removing it) to avoid getting sprayed, avoiding the urine spraying onto our shoes (not to mention the possibility of either side of the dirt hole collapsing under our feet, which has been known to happen), and hoping that the stream would not divert so far in its strength as to run down one leg or another.
And the bats, of course. And large spiders. And the toilet paper falling onto the dirt ground (which somehow, I didn't mind as much as I would mind toilet paper falling onto the floor of a public restroom in the Western world). But I suppose those were more equal-opportunity annoyances.
