Just had installed an induction hob -- still flat ceramic, but this time completely flat, no dials knobs or anything except a completely flat low rectangle that looks like glass. All controls are by touch.
And the cooking is nothing like the old hob. Instant power on and off -- just like gas cooking except when pan is off the hob there is no heat. In fact the surface doesn't get hot except by heat coming back off the pan -- like a trivet gets hot if you put a hot pan on it. So you can put your hand on the hob where a boiling pan has just been removed and its warm but doesn't burn you.
I can't get over just how instant it is
According to the (often unreliable) Wikipedia induction hobs are twice as efficient as gas, but for me I get gas like speed with electric cleaness and ease.
One drawback is that because it works via a magnetic field your pans muct be magnetic -- turns out my set of newish stainless steel pans are not (test with a fridge magnet).
A really neat trick: I've got a silicone disc I use as a trivet. Put that on the hob, put a pan on top of it and you still can boil water in the pan
