We have a microwave at work, I used it once and it took me 5 minutes do actually make it do something. It is like someone just slapped some buttons and dials and a display on there without thought and created some twisted logic just to annoy the user.

I only ever bought two dial microwaves. Power and time, two variables, easy to understand and intuitive.

Granted, I might try the microwave Technology Connections demonstrated [0] because it sounds like it actually works.. but no chance of getting an old model where I live... or anywhere else.
