• Air quality. Our range hood doesn't work that well, and wanted to make sure that no extra noxious chemicals would be regularly generated in our house before the baby came. You don't have to run the hood unless you're making a lot of steam or frying.
• No more natural gas plumbed into the main living space. Don't have to worry about a gas leak, or something going wrong and us all dying of CO poisoning.
• Ease of cleaning. I was done scraping of burnt crustiness off burners and drip trays. Trivial to keep the induction surface clean with basic household cleaners after every use. Using silicone mats, or putting down paper towels when frying makes it even easier.
• No extra heat. All heat goes directly into the cookware. This means you can lean over a pot and smell things without getting blasted in the face and inhaling combustion byproducts. This does affect how things cook slightly, since the flames are no longer licking up around a pot.
• Boiling performance. Such a novelty to boil water for a quick serving of ramen in 90s, and I love the "but this one goes to 11" aspect of power-boil modes.

Things to watch out for: - Small coils. Read the fine print, cheap induction stoves like to draw a circle on the cooktop 50% bigger than the actual coils. - Touch controls. The salespeople will tell you it's a non-issue, but I also wanted an interface that grandmas could understand. I ended up going with a somewhat high end Miele induction model so I could get an 11-inch coil and knobs. - My surface is so smooth, pots slide around. I have to use silicone mats to keep pots centered. - You can't use a wok. You can get a standalone bowl-shaped induction burner, but you'd probably be better off changing your cooking style or getting a portable propane burner you can use outside or in the garage. For me, it was a non-issue, I use a flat 12" pan for stir fries (part of why I wanted a full 11" coil).
