Talking about knobs on stoves and UX - I never understood why American stoves have the knobs on a panel at the back of the stove instead of at the front. Isn't it inconvenient having to reach over hot, frying, steaming pots and pans?
But ovens with controls in the front are definitely available in the US. So you can have whatever style you want.
I agree, though, it is stupid when they are in the back. Presumedly this is just to save money by putting all the controls and displays in one place.
Still, those are better than buttons.
