I got one over the summer, when we remodeled our kitchen. I love it--it heats water amazingly fast! As in, if you stick your finger in the pot, you can feel the temperature rise.
That said, it has its quirks. Since mine is new, it's all digital, and the technique I've used to cook pasta for the past 45 years or so had to be altered. Hardly life-changing, but since it responds instantly, you can't, say, turn off the burner a couple minutes early and let the pasta "coast down" as my dad used to say. Once the water is boiling and I add the pasta, I have to ratchet down the temp--from P (Power heat) to 7 to 5 down to 3, every 30 seconds or so. It's not a big deal, just something I had to get used to. It has different sized burners, and one is adjustable sized, so it will fit whatever pan. The burners will not heat if there's no pan on them (and my stove beeps at me if I try).
As to pots--you need pots that are stainless or explicitly say they're for induction burners. Induction works by magnets, so if a magnet won't stick to it, it won't work. My Revereware, with the copper bottoms, don't work. My All-Clad does--you just have to check. I also have some Copper Chef that works fine.
