They let you produce SD-card images with custom NixOS'es.

Very useful when you want an exact software layout, and exact system settings, like what user accounts and SSH keys to include, what systemd services should run, what directories should be tmpfs, and how to interact with the local network using avahi.

Conveniently for me, they keep releasing things right as I start to have an interest in using that thing.

I appreciate that RPi is trying to make the ecosystem more accessible for newcomers - but not at the cost of power users, please!

Raspberry Pi continues to show that its real value is in continuous software and community support.

Even if their hardware isn't the greatest value, the software always shines.
