We develop a sustainable mobile OS
It is 2017. Pick an average PC from 2007 and install a minimal Linux based operating system. You will be able
to do basic computing tasks (eg. surfing the web, reading E-Mails, listening to music, chatting) just like on an
expensive modern PC. You will even get security updates, so your old computer is protected, just like as a new
one.
On the current mobile landscape you get none of this. Even if you buy a very expensive phone you will only get
two years of support if you're lucky. But if you treat your smartphone as a real Linux system and use a
distribution instead of a "ROM" and use a package manager instead of a "store" you can just keep using your
devices until they break.
