What exactly would you use it for? Not trying to be negative, I'm just not sure what would be worth typing out on a phone keyboard on the go, instead of waiting until I have access to an actual keyboard. I guess if you have a keyboard for your phone that's also different. (so for android tablets etc this is great)
Chromebook
I'm still waiting for Amazon to restock after I saw this post go up: https://blog.lessonslearned.org/building-a-more-secure-devel...
On my chromebook I use crouton[1], which is arguably more "native". You get an Ubuntu install in a chroot and can even run X11 apps in a chrome window. I was even able to compile neovim, you just need to set it up to use the system's lua and luarocks.
