Hi again,

some thoughts about a „pyraPhone“:

Yeah, the cores should limited on 1ghz. maybe with manual switch to 1.5 / when connected to power cord.
As UI e17 or KDE Plasma mobile or even Sailfish OS.
A pyraPhone should be also have connectors for additional hardware like the moto z / original jolla phone - so it doesn’t need a slider keyboard build in for example: it could be added later.

i think after the librem 5 crowdfunding it is difficult to get enough backers. 
But with the experience/references it would be possible - even more after the pyra is released!
