Siri, Google Now and Cortana are digital voice assistants people can use to communicate to their smart phone. Some people think these are great tools. Others think it's kinda creepy to speak to a machine as if it were a real person. What say you?
I have used Siri in the past, but really never found it useful. As for now, Siri is disabled on my phone.
I use Cortana sometimes. It's fun but not useful. And it offers search results from Bing. I use Google for search results.
