Microwave with knobs: put food in and turn the knob to the time you want. maybe turn the power knob if necessary, and wait for the ding
Microwave with buttons: put food in, stare at the keypad for 30s looking for the "just f**ing microwave it" button, give up, start putting in a time, realise you need to put in a power first, work out the appropriate power in percent based on the excessive power of the microwave, put that in, figure out the expected format for the time (60 or 100 for one minute?), put that in, press start, wait for the interminable beeping, have to go and press a button to shut it up when you're busy with something else
An exaggeration, but most button microwaves have at least one wacky and annoying issue in their UI, and i've experienced all those problems separately. The panasonic inverter ones with a convection oven are worth tolerating just for the quick yet crispy baked potato option, though.
