One of Motorola's more intriguing prototype concepts was the Project Ara modular phone. As it turns out, that was one of the things which Google kept for themselves after selling Moto to Lenovo. Apparently, not only is Project Ara farther along than anticipated, it might actually be put into production for a launch next year. Google has announced a couple of intriguing details regarding the "out of the box" lego-style phone concept.
First, the retail price target that Google is shooting for when they finally launch the device is $50 for the entry level version. That will be for the main display, frame and a WiFi radio to get started. Afterwards you can hit a kiosk to buy an additional add-on pieces you might desire. Google will obviously provide the software which users will be able to customize (most likely based on Android). Google knows that it will be tough to hit that extremely affordable target and still make a competitive device, but at least they are planning ahead.
The second thing that we know about it is that Google has announced a developer's conference set for the device for April 15-16th. This means they aren't messing around and plan to try and bring it to market as soon as possible. It will be interesting to see just how well Project Ara develops. We will keep a close watch on this and share any new details.
