Product review (5 stars): GE Cafe 36" Induction Cooktop
It's been 30 years since I have owned a gas cooktop.  So comparisons to gas are unhelpful.  This is the best electric cooktop I've ever had.  Heats quickly and is much easier to control than radiant and coil.  The controls are a little unusual but after a month or so I've gotten used to them.  The biggest problem is just how sensitive the controls are.  The controls will try to turn on burners when you put anything on the surface above the burner power button.  Of course nothing happens since the absence of a pot prevents the burner from activating.  Nothing gets hot.  So the downside is minimal.  But still the constant beeping can be annoying.
Surface contaminants (water, oil, etc) interfere with the controls.  If the surface is wet or has a slight haze (residue of grease on the cooking surface) the controls will not activate when touched.  This can be inconvenient and hard to predict.
The electronics do a great job of maintaining temperature over time.  There are no indications of burner cycling (change in rate of boil) as I've seen with previous radiant cooktops, etc.  Pots don't seem to develop hot spots.  Burner recovery is very quick and allows food to be seared or browned instead of steamed.
Would have preferred black but this was only offered in gray.  We did have to replace many old pots and pans.  OTOH a new set of pots every thirty years doesn't seem excessive, right?  The old pots were donated and will live on in someone else's kitchen.  No harm done.
So far so good.  I've really enjoyed cooking on this stove.  Highly recommended if you can live with the unusual controls and beeping sounds.
