Listen up, Sony -- we want Nigel!

Sony's Concept N products have been sneak-peeked as future possibilities. His name is Nigel, but I'm guessing you haven't heard of him. Nigel could be Sony's answer to Apple's Siri, Amazon's Alexa and Samsung's Bixby, a personal digital assistant that could potentially be a competitive threat and big boost to the company. But Sony has him way under wraps. I recently paid a visit to "Sony City," in Tokyo, where the electronics giant has its corporate headquarters.
