I owned every generation of Raspberry Pi and I still use the 5, 4, 3, and even a 2 Model B. Their software/ecosystem support is unmatched by any other SBC line.

My pair of RockPro64s refuse to go to the drawer. Every time they are about to retire something comes up that is the perfect job for those machines.

One is currently running Scripted to integrate my unifi cameras to HomeKit. Zero fans.

I've equipped the other one with 2 beefy 22TB HDDs, Tailscale and Minio. I'll send to my parent's house to act as remote backups.
