@JustineSmithies #Librem5 with #PureOS for about a year now, and a pinephone (and then a pro) since mid 2020. Most of my usage is Calls, Chatty, Clock, #Firefox, and #Tuba. I bemoan the lack of a good Matrix client (Chatty hates my server, Fractal next and Fluffychat are both buggy). #Cantata for music and mpd remote. Todos, Millipixels, Vvmd, Calendar and PureMaps occasionally get use. Evolution is my email client since (i) my org forces EWS and (ii) Geary lacks crypto signatures.
@mamichel1 @JustineSmithies Not really. It's usable in a pinch. Unfortunately, my org regularly gets "Help I can't talk right now but buy me some gift cards plz" scams, so S/MIME and/or GPG are a must. Geary is the better mobile client but doesn't support those.
