> Microwave ovens should have a knob-button combo that I can work in 0.5 seconds without looking or reading the manual. We have a microwave with a knob to set the duration and another to set the clock, with two small buttons (one is 12/24 hours, the other I can't remember). Every guest we had who tried to use the microwaive failed it, because it was so not intuitive to just turn to set the duration ... and then wait a couple seconds before heating starts automatically. I wish there was a physical start button.
