But are there any actual FOSS ROMs on it?

Not many though, a few Samsung and then the pixel tablet as far as I know and they’re still a bit more than $150 even used usually

https://extensions.gnome.org/extension/307/dash-to-dock/

I use this and its worked great

That’s my hope too, that doing it for Ubuntu means other distros can ride the coat tails, fingers crossed for Fedora

I used it for years and loved it but after a while the reinstall for every upgrade sucked and I ditched it and went to GNOME Fedora. I mean honestly Debian with GNOME is probably good enough but if you really wanted to you could install the pantheon desktop environment

Lineage is just android

Huge on lineage myself, think its dope
