Raspberry Pi Phone
Value Proposition
The value proposition of a DIY smart phone must be low cost and infinite variability, with decent performance, and definite lifetime of service via replaceable parts. Different modules would be time lapse cameras, long battery life, solar operation, outdoor use, GoPro use, etc.
Perhaps regressing to "a small computer" with any desirable application, such as smart phone with camera, is a valuable positioning statement.
This could be made valuable when well-designed 3D printed parts bring the phone into a nice package.
