Not gp, but I have a PinePhone Braveheart currently running Fedora. Battery life and lack of apps is what prevents me. I listen to a lot of podcasts and audiobooks so the UX around those is really important to me. Other than that I could live full time in the PinePhone (and be really happy with terminal access).

Battery life will get there, as will apps I'm sure. The real killer feature will be when Android apps are runnable.

I probably need to spend a bit of time determining what apps in my must-haves have workable options on PinePhone yet. The last Ubuntu Touch build I played with was very sluggish, but I've heard really good things about more recent ones. OTA is a big deal, since re-flashing my phone to get software updates is not a workable solution for me.

Probably the toughest thing to lose will be my bank's app... I was used to not having it when I was on Windows Mobile, but mobile check desposit has been really nice to have since I've been on my little iPhone lifeboat.

The main thing keeping me from using it as my daily driver is the battery, as others are reporting. Secondarily I'm working through an issue where I can receive calls but not place them which is also frustrating. I would also like to finish building apps for many of my IoT appliances so I can continue monitoring them on the go, like my smart thermostat.
