PinePhone
I really wanted to like the PinePhone, when I got mine, I tried Mobian, which had the Phosh shell and that was weird. Some things you tapped, some you swiped. I really liked the Ubuntu Touch, but it barely supported any of the phones feature; and settled on KDE Plasma Mobile for a while. That was really nice too... Then came the "oh, all my friends and family use WhatsApp", and back on Android we go...
I don't know if Waydroid ever made significant progress, but the PinePhone always felt sluggish, and if they've dropped the higher spec one, then it's going to really struggle. And that's a shame.
