One company is trying to sell a smartwatch that powers phones, tablets, TVs, and more

Near the end of 2013, a company called Neptune came out with a crazy idea: build a playing card deck-sized smartwatch that could run without a smartphone. Now the company is back with a much more ambitious, yet equally crazy project to reimagine not just the smartwatch, but your phone and tablet too. Yet where every major company with a smartwatch (short of Samsung), has put the heavy lifting on people's smartphones for things like network connectivity and apps, Neptune wants to put it on your wrist. In the middle of it all is a wrap-around, water-resistant smartwatch called "the hub," which has a 2.4-inch capacitive touchscreen, a 3G/LTE modem that works with nano-SIM cards, and runs Android 5.0 Lollipop.
