I just installed the latest Postmarket OS (with Phosh) on a Pinephone and goodness they have come a long way.
The OS is basically usable. Which is amazing on such an underpowered device.
Also, convergence worked for me for the first time :) And yeah, I could easily use this with Helix Editor + git for development work on the go. (Keep in mind my daily dev machine is a 16-core desktop with 64GB RAM. So, no, it’s not the same experience. But is it usable? Heck yes.)
