How do "infinite zones" in induction cookers work?
As far as I can tell, this means coil sections are added and removed to couple efficiently to the pot currently in use, monitoring whether power is being drawn or not. It is a bit nicer than having to be as aware of minimum/maximum pot radius for each inductor, which requires a bit if attention on my induction range.

Pick your price/features trade-off...

(I do like induction, generally; it behaves much more like gas in its immediate controllability, and you can do silly tricks like cooking with a paper towel between stove and pot to catch splashes... but remember that it probably will require a few hundred more dollars to replace nonmagnetic pots.)
