I find them extremely practical on my induction stove: it's a single perfectly smooth glass surface, which makes it a joy to clean.
Physical buttons (or any 3-D feature really) and food preparation make cleaning a hassle.
I prefer physical buttons, or better yet knobs I can remove and soak to clean. My range has capacitive buttons for its oven controls, and every time I wipe it down with a damp sponge every button is triggered along with a cacophony of beeps. It could disregard inputs when multiple are registered in quick succession, but then each button would have to have a delay before action to see if it was pressed individually, and of course rapid legitimate use would pose a problem (as in the iOS calculator issue).
