Heat storage effect -as soon as you put anything in cold in the pan the whole element goes cold and it takes ages to reheat. Unlike a gas flame.

And "induction" heating is 90% conduction - only a tiny part of the pan is inducted and then the heat has to conduct to the rest of the pan. So in some ways its worse than a conventional electric hob because the heating is so uneven, and you still get the heat storage effect.
