A few other advantages to induction:

1. Better air quality. You don't have combustion byproducts in the kitchen.

2. More efficient than both gas and conventional electric stoves.

3. Faster to heat than gas/conventional electric (due to the efficiency improvement)

4. Easier to clean (except for glass top stoves).

I've yet to own a full-on induction stove, but I do regularly use the 120V induction hot plates in my kitchen. In fact, I use them more than the gas stove that came with my house. I'm eagerly awaiting the day that I have a full induction stove.
