Frowny-faced USB adapters? They're the future, says Motorola. The company has just posted a teaser video inviting us all to "Stay Unplugged," featuring an animated USB brick that will break your heart as it sheds a single tear. What does this mean? Wireless power is going to be a big part of the company's CES plans, we'd say, but we'll all have to wait and see the details. In the interim, don't feel bad for the poor thing. It is, after all, a vampire.
