I have one running home assistant, I have one running a duet web server for a printer, and I have one that runs cncjs for a mill.

the home assistant one runs a reverse proxy and adguard/tailscale docker among other things.

they're useful but the price point sucks right now unless you absolutely need the IO ports/shields they provide. I have a PoE shield on my home assistant one that makes the installation very tidy.

My longest running Raspberry Pis are using HifiBerry HATs. Acting as SnapCast clients, forming a poor man's Sonos system throughout the house. The oldest running Pi is a 2.
