Is anyone building a RasberryPi powered cellphone? Basically something that has a battery + solar panel + touch screen. A device that is fully operational without any need of peripherals.
Or I guess a more useful device would be a laptop. A chromebook equivalent but powered by rasberry pi and is hopefully kid-proof rugged
I have seen some designs, not sure how much to fruition they've been brought (afair they were still in crowdfunding stages). You'll still never own the baseband though, but would have some degree of freedom and/or learning experience.
Pitops exist for laptops and there's also some peli case style solutions iirc
