Yeah, we need to get back to modular design with replaceable/upgradeable modules or components … any other type is unnecessarily wasteful.
Not 100% convinced it would work in something as small as a phone yet though … but the concept is good, and certainly could be applied right now to slightly larger devices.
Mad Penguin previously mentioned a modular smartphone concept, but I think he was envisioning replaceable internal components, more like a desktop PC.
(which may work better for something the size of a phone)
With that phone you linked to I have a crazy image in my head of dropping the thing just as the bus you’re on gets to your bus stop … and having to spend half an hour looking under seats for all the modules
