Well, generally speaking, most people discussing the benefits of appliances and stuff with turn dials are referring to older/simpler appliances, back before they started adding in unnecessary electronics and ‘features’ and stuff.
i don’t know why you’d assume that. lots of current/new appliances are still made with dials and knobs. in fact, most are.
also, you’re the only one here discussing microwaves. so far, others and myself have been discussing refrigerators and laundry appliances.
