The kitchen gadgets you should buy (and the ones you can skip)

With so many connected devices making their way into our living rooms and bedrooms and onto our persons, it was no surprise when gadgets started making their way into our kitchens. You can buy so many WiFi- or Bluetooth-enabled widgets to help out with your cooking now, from smart Crock-Pots to app-controlled cooktops. Some are pretty dumb -- who really needs a toaster that pings your phone to say it's done even though it literally only takes three minutes? A smart thermometer that tells you when your pork roast is at optimal temperature after hours and hours of slow cooking makes a little more sense. However, you only have so much counter space, so you better choose wisely when it comes to adding new tech to your kitchen.
