The Nexus products, which will hit store shelves in November, also will compete against a variety of other phones and tablets that run on the free Android software, including popular devices made by Samsung Electronics.     

Both of the Nexus devices will run on a new version of Google's Android operating system. The latest software is called "Lollipop" in keeping with Google's tradition of naming its Android upgrades after treats.
