I feel like 80% of the microwave's downfall was adopting VCR-like push button interfaces.
The two dial microwave was peak UX. Quick, painless, no wondering what sequence to press on a strange 'wave, zero time delay between input and cooking, and easy use of the (essential) power function.
It even lets you change time or power mid-cook. For maximum laziness it's possible to leave the door cracked with time on the dial, throw in the food, and adjust the dial while it's already on (slightly reducing the wait before eating). Using the microwave becomes forgiving instead of foreboding, because it's so easy to change your mind.
The only downside is that it's slightly less precise, but getting the exact time down to the second is probably less important than you think. It's also a mechanical part to fail, but I've had microwaves die because the push buttons failed too, whereas my dial unit is still going strong. YMMV
We are repeating this same UX mistake with induction hobs now.
May I recommend the excellent, push-button-deprived IKEA Tillreda? https://applink.ikea.com/tY8M9r9M4w--80511549--ca--fr
Peak microwave UX is today, IMO — modern commercial microwaves. You seem like my people, so check this out — https://shop.sharpusa.com/medium-duty-commercial-microwave-o...
Consumer-grade microwaves are made to look cool, not to use. Commercial microwaves are made to make money. One dial, no bullshit.
And check out the scale on the dial. That’s modern, no old-skool 2-dial microwaves can do that, AFAIK.
I quite like how mine has a rotary knob that sets preset programmes (which I never use) but also you just tap it to increase the time in 30 second increments. Tap tap tap - wait - <HUUMMMMMM> and it's on for a minute and a half.
I do prefer the mechanical wind-up timers though.
There are some use cases where exact time is very important. Warming milk for a baby for instance - it’s pretty low volume and the difference between 30s and 40s is huge. I used to favour the 2 knob microwave, but since having to do that a lot I’d always choose a digital timer. Some have decent interfaces.
