LG showed off their new LFX31945ST door-in-door fridge at the 2012 Consumer Electronics Show. Amidst the "smart" fridges with touch screens and WiFi, this fridge had a simple innovation: a smaller door on the front of the fridge that allows access to a limited selection of shelves. One can store juice, milk or beer in there and reach them without opening up the entire fridge. Whether the innovation will become popular -- and how much it will cost -- remains to be seen.
