Coffee mugs: why?

Okay; so, in the office, they're acceptable. And everybody knows that people who have real jobs that require real work use Thermos bottles. But why would anybody use coffee mugs at home? Will the saucer become extinct? More and more cheap sets of dishes omit that fancy cup-and-saucer option and provide a mug only. I come from a long line of people who prefer coffee in its unadulterated form, but one can't help but wonder: what do the people who use cream or sugar or their odious substitutes do with their spoons? Or are coffee stirrers coming into home use? By the way, a Google on "disappearing saucers" brings up mysterious UFO occurrences.
