Unnecessary tech in kitchen appliances. Ovens, dishwashers and washer/dryers. I spend most of my time battling the user interface or dealing with obscure bugs.
Put power dial where you want it. Put timer dial where you want it. Timer starts ticking down and the microwave turns on. Loud ding (from a physical bell somewhere inside it, not a speaker) when it's done. That's the entire thing. No buttons, no clock (god, why do you need a clock on your microwave?!) none of that shit.
Heavy, good-feeling dials that you could feel physically operating something underneath, from the clunks of the power dial to the subtle scrape of the timer dial. Great feel on the door handle. All-around solid. Nothing to learn. Just use it.
