Inspired by @mz I've finally managed to flash #mobilenixos to the #pinephone which I didn't use since autumn. Well, it works, although not exactly usable as a phone, at least in the example Xfce configuration. Actually I was surprised that Xfce is *theoretically* usable on the mobiles - it has an on-screen keyboard, a touchscreen mode for mouse and can position windows fullscreen by default.
