For me a personal phone is one where I dictate what to share and what not.
Freedom in the sense that I can choose to use no cloud, my personal one, or a more public one.

Freedom to install apps I want, so for this we still need to look at anbox or the likes as app devs wont quickly develop for UBports.

And then there is battery life... Should not be worst then the default OS.
Lastly a nice and friendly GUI, but Ubuntu Touch does it best.

But the real reason for me to be here aside the personal aspect is convergence. One device. My dream.
