My grandma microwave (that was supposed to be shiny new cool awesome microwave) had no keyboard, all numbers were input with a stupid knob that you would turn forever. But even worse, it would only work if you input the desired time and power... AND YOU HAD TO PRESS BUTTONS FOR THOSE. Yes, neither of them were default, you had to seek for a "time" button, press it, then turn the knob, then seek the power button, press it, turn the knob, and if you did it wrong it would get into some weird states of waiting for a certain input that it was not clear what it wanted, and it was not clear how you could cancel it (it does have a cancel button, but it took me a while to realize I had to press it several times in a row to reset the thing so I could try again). The microwave is so annoying that in the end I gave up and don't used it anymore, I only relied on food that was palatable without heating, or I used the old fashioned fire. EDIT: I remembered another one: also had no number pad, instead it featured the following buttons (that required some good force to register a press): +5 seconds, +10 seconds, +30 seconds. Wanted to make a lasagna that take 16 minutes? Good luck.
