I have many Pi's, but basically it's a middle ground between PC and ESP, if you need HDMI but not much power then it's a good choice..
- RetroPi - Pi 3B
- 2xRunning Pi Signage (Pi Zero 2 / Pi 3B)
- Zabbix and Grafana for home lab monitoring (Pi 4 - will be moved to a VM once I pull my finger out)
- Pi Zero 2 - Klipper / Fluidd (3D Printing)
- Robot Octo Spider - Pi 4 (It was a gift as I like robotics)
- Pi 1 - no longer in use but controlled Christmas tree lighting with sync'd audio
However at today's prices they are not a great idea, although get on a legit wait list for a Pi Zero 2W and the bang for buck is great (equivalent to a 3B mostly)
