I use it for work by choice, it’s fine. We can use Chrome, Edge or Firefox. Edge is basically a clone of Chrome but it integrates better with our MS account & applications and it seems to be better optimized for Windows 11.

Any newer Pi should be fine for a basic setup. I ran HA on a raspberry pi 3 B for years with no performance issues.

No way, I wouldn’t work for a manager I don’t trust.
