Hands-on: Sony N is a Google Glass for your neck, with an assistant named Nigel

Sony hasn't said why it named its new wearable "N." Or for "never," as in when you'll be able to buy it. Or maybe "N" just stands for "novel." Because we've simply never seen a wearable that drapes across the back of your neck, blasts music up into your ears, and alerts you that one of your favorite bands is playing the dive bar on the next block. And we may never see it, because it's just a prototype--but one you can help test, too.
