I have it in nix and use the postrgesql backup config + borg in nixos to move the database and files on another host for backups. I would say it is not too complicated as long as you dont want to have it fully declarative (i sill manage users and apps in nextcloud itself).

Can confirm, am using the remarkable tablet to read a lot of academic papers. The only thing to keep in mind though is that the best experience is that apparently you need good enough vision to be able to read the article without zooming, some people I know struggled with this. However with normal sight, I basically only zoom to note something in the article if there is not enough space to note it down otherwise.

I use the following a lot:

• Nextcloud for files, calendar and contacts
• synapse + a few brudges for IM
• mail server
• tandoor for recipes and grocery shopping lists
• gitea
• wireguard
• miniflux
• rmfakecloud And from time to time:
• jellyfin
• wallabag

Tandoor is imho somewhat overlooked and really nice.
