Of course another accessory for the Pixel (or anyone, really) is the new Google Home. This is an entirely new category for Google that aims to bring Google Search, Google's computer learning, and Google Assistant into our homes and lives.
Similar to Amazon Alexa, the Google Home device is always listening and ready to help, but not in a creepy way. Ask for information about your day, calendar information, weather or traffic reports. Make differ reservations, turn on lights in your smart house and more all with your voice and Google Home. There is so much it can do we can't explain it all. It isn't necessarily an accessory for the Pixel, but will be a great addition to any users collection.
