Since nearly all the important pros and cons are already listed, I just want to add one more thing:
Induction cooking produces electro-magnetic hazards. It doesn't seem to be quite clear what possible effects that may cause on human body (e.g. radiation that hits your eyes). Some say none, some say there may be effects ... Just like the question wether or not a mobile phone may be harmfull to your brain while doing a phone call.
Same for the stuff you put in the pan that is exposed to this radiation. It could be possible that it may influence the food's structure/molecules.
