Some people would process their most critical files on their cell phone if you let them. These devices have non-ECC memory, thermal concerns (that can result in component failure at the worst moment), SD card connector issues and the big one vulnerability to static and dust due to the numerous horsepucky enclosures. That said, they can be great for media, I/O (erm, IoT) controllers, and compute servers (on non mission-critical data, like analyzing pedestrian traffic but not like recalculating the b-tree on a database containing life/business data). Of course, the Sun could always go back into another 10 year period of decreasing CME’s ..not that the technicians promoting anecdotal would realize lol
Your comment is very difficult to understand...are you suggesting people could repurpose cell-phones for projects you would normally run on a raspberry pi?
