> two dials. One is time, the other is power cycle
This is the ideal design and no one can convince me otherwise. Same thing goes for ovens. All I care about is "how hot do I cook/bake this?" and "For how long?"
Personally I really like the sensor modes of my microwave. For most of my leftovers, I can toss the plate/bowl in the microwave, hit REHEAT, and it figures it out. If it thinks I need to stir/rotate, it'll beep at me to do so while its cooking. Seems a lot simpler as a user than thinking about how long to cook it, what power level, etc.

Two dials is perfect.
