pi 3B+, 4, 5

[lcipher3]

Get the Pi-5 w/official cooler and PSU.

- Option for ultra low Idle power at shutdown means you never have to pull the plug.
- Super convenient power button
- No HDMI or DSI display issues as we have with the Pi3
- PCIe port for attaching NVMe or SATA controllers

Did not think about the power button - that would be super nice:  are there points in the moode exit (or pi 5 exit?) that could run a py script to say something like "shutdown complete" on a display etc?

And the NVMe is interesting.
