>>wicket+(OP)
I'm a very happy Sailfish OS user, since 2016, before that Meego, Maemo (Nokia N900, N9). I do have an android phone for one App (Deutsche Post) which I use only when I need to ship stuff. Running on a Gigaset (made in Germany, 4KmA battery) I generally get two days of usage, 1 day if I'm stuck on Mastodon.
From being able to do SDL2 stuff (Godot 3.5 for instance) with a wayland compositor to just not having f'ked UI, I'm happy. The challenge of getting more apps is certainly a challenge. But that's good, gives me lots to do.
