The Duofone concept features two phones that can be used separately just like regular cell phones. But when you want to watch a movie or TV show on your phone, you can dock them together to create a double-wide display. Even better, when one of the pair is running low on battery power, you can connect them to share juice. And maybe the cutest feature of all: they dock on their charger just like a couple spooning in bed. Awww.
