I remember those days - I liked our microwave with just a time knob and a start knob.
But it had its drawbacks. My young children couldn't set the time to heat their oatmeal. "Turn it to 1 minute". They'd twist the knob and say "Is that enough?" Without knowing enough about time they couldn't (yet) figure out to turn right or left to get to the right number.
With a digital one, they'd just poke 1,0,0 and hit start.
