Technology and innovation are amazing. It's why we do what we do here at Engadget every day. But it's all for naught if the electricity goes. There was no reminder of this more timely or apt than a huge power failure at CES on Wednesday. Exhibitors got angry, attendees got confused and companies got spicy on Twitter (oh, brands!). That didn't stop us checking out the best of the rest so far though. Enjoy.
