Very interesting, I haven’t heard about it before, but just stumbled over an article about an operating system (in development) that is a convertible for Android based smartphones. It currently bases on Andoid 5.1, but connected to display & other peripherals turns into a debian based desktop system.
For me as a Debian user this sounds just too perfect
So far it is only available as a beta version for Nexus 5.
But that would be definitely something I would be interested if further advanced.
As far as I know there are already some Debian packages ported for the ARM architecture, which can be used for example through Lil’ Debi (another interesting project, bringing Debian to your smartphone), such as for example Libre Office or Thunderbird.
Anyhow, Maru OS is definitely something that sounds super exciting to me and if it was available for my FP2 I’d immediately try it out!
