A lot of the interest in the Samsung Family Hub stems from the enormous, 21.5-inch touchscreen (about 55cm) on the right refrigerator door. On it, you'll find a variety of apps for things like streaming music, managing your family's calendars and ordering groceries for delivery.
Yep, those are cameras, and they snap a picture of your food every time the door closes. If you're at the grocery store and you can't remember whether you need more milk, you can pull out your phone and check.
Next up, the Whirlpool Smart French Door Refrigerator. No giant touchscreen here, but it does boast Wi-Fi connectivity that allows it to send you alerts when the power goes out or when the filter needs to be replaced. You can also sync it up with the Nest Learning Thermostat.
The main attraction is, again, on that upper right door. Instead of a touchscreen, LG went with a special panel that goes transparent when you knock on it. That'll let you see your groceries without needing to open the door.
