pH meters

From: Jan Paris <jparis>

is there any real advantage of the sort of flat push panel on the pH
meters over the knobs if both of the machines are digital? i had a
vendor say there was and i really don't like the guy but he may KNOW
something, though i doubt it's much if he does!  anyway, should i
consider that?
