Exactly.
My first GPS (Garmin 12), had no mapping capability at all. It simply reported a position. I then needed to find that position on a quad. And the easiest way to make that position info useful for actual navigation, was if it were in UTM. But for a lot of the younger folks, the GPS "is it" and I can see how the coord format really wouldn't make any difference. But when the coords actually are "it", and you need to actually "use" them, decimal/degrees just sucks azz... While UTM is easy-easy.
