I personally do not find squatting any problem at all. As for privacy, well, if anyone wants to look, so what. And the night excursions are good excuses to look at the stars! The only time I have seen that you guys have an advantage is when I have to be in a climbing harness all day on a vertical wall. All those gagets are primarily for pretty specific situations - such as being at 20,000 feet on Mt. Everest in a storm when everyone has to pee into a bottle. Methinks, you think our "burden" is really more than it really is.
