From Google’s Project Ara Web site:

The smartphone is one of the most empowering and intimate objects in our lives. Yet most of us have little say in how the device is made, what it does, and how it looks. And 5 billion of us don’t have one. What if you could make thoughtful choices about exactly what your phone does, and use it as a creative canvas to tell your own story?

Introducing Project Ara.

Designed exclusively for 6 billion people.
