Pro Modular design
Project Ara introduces the concept of interchangeable hardware parts to a phone. This would allow you to choose parts of the phone based on your personal preference, task priorities and situational needs. For example you could choose a longer battery over a better camera, or add a physical qwerty keyboard, or a solar panel. You can even swap the screen for another.
Pro Opens the door for never before seen use-cases for a phone
Project Ara would allow for using a phone in ways that simply don't make sense currently, like turning it into a projector, or a Geiger counter, or a clamshell gaming device. There could also be scientific, medical and industry specific modules, and many, many, more ways of using this device that are not possible currently.
Pro Hot-swapping of modules
With Ara you change hardware parts without needing to power down. Even battery modules can be hot-swapped because the frame itself holds enough power to operate for a small amount of time.
Pro Print your module cases
3D Systems make 3D-printing equipment and have partnered with Project Ara to create a continuous 3D printer that can quickly print large amounts of Ara module enclosures. Going forward, it's possible that multiple part of a typical manufacturing process could be delegated to 3D printers.
Pro Can be used as a $50 Wi-Fi device
A $50 version of the phone, that consists only of modules that are required for it to work, bypassing even a cellular connection, instead having an internet connection over Wi-Fi, is planned.
Pro Module ecosystem has the potential to become highly competitive
Project Ara would allow for a module ecosystem that resembles current app ecosystem in pace and level of innovation, that's highly competitive and offers branded hardware parts.
Pro Plans to connect the next 5 billion people
Long-term program objectives of Project Ara include delivering mobile internet to the next 5 billion people.
Pro Available soon
Developers can sign up to get the phone in the coming weeks and a "market pilot" is expected next year.
Pro Comes in three sizes
The aluminum skeleton ('endo') for the phone is available in 'mini', 'medium' and 'jumbo' sizes.
