* Personal workstation/gaming machine
* Employer provided work laptop (MBP)
* Surface Go Tablet used for reading around the house, light travel, etc.
* Personal Dell laptop used for longer travel
* Old desktop converted to a server for running services I always need up.
* A rpi 3b used for running services I want to physically separate from the internet accessible main server.

So I'm not far off 7. Other tech-heavy users may have seperate devices for their spouse/kids, or dedicated devices for specific OSes (my main workstation is a dual boot, my laptop is linux only and the tablet is windows only). So I can see a path to 10 for others.
