Induction cooking, the surfaces DO get hot, pull a lid off and see a bit of steam convert to water and drop and sizzle on the stove and make sure your hand is far enough back from the edge of the rag you are trying to get it up with.
An older induction I saw, all the burners were the same size. I believe commercial ones are larger and my and my parents stoves have two different sized burners.
I do think preheat on the oven is quicker with electric verses gas in my experience. Also think electric is generally more even temperature, as gas can fluctuate more based on neighborhood usage (winter when all the furnaces are going).
