If you want to get elaborate with your cooking and try a griddle or a sous vide, you normally need either a dedicated machine or a bulky add-on to get things right. You won't have that hassle with GE's 2015 Cafe, Monogram and Profile cooktops, though. They're already pretty high-tech between their safer induction cooking pads and touch-sensitive controls, but the real stars of the show are their abilities to switch to other cooking methods with little effort. The Cafe and Monogram models have an integrated griddle (the first for induction), and all three can use a $150 smartphone-controlled sous vide accessory (also a first) that lets you get just the right water temperature without having to watch like a hawk. Just be prepared to pony up if you're hoping for the latest in culinary tech. GE's cooktops will start at $1,500 for a 30-inch Profile, and they scale all the way to $3,100 for the 36-inch Monogram.
