Google’s Project Ara isn’t the only hope for phones with replaceable and upgradeable parts. Finland’s Circular Devices is developing an alternative concept called the Puzzlephone, which breaks the handset down into three constituent elements. The phone’s Spine provides the LCD, speakers and basic structure, its Heart contains the battery and secondary electronics, and its Brain has the processor and camera modules.”
The concept of a modular smartphone seems to be attracting more attention. Interesting.
