So true. Started with a couple AC AP PRO (incredible by the way). Ended up with an edgerouter poe and a poe unifi switch. I'm running the control on a vm on qemu/kvm and the seamless integration is wonderful. Once I plugged in the switch it popped up in the devices section and I could perform a one-click software upgrade, just like the WAP.

I will say that the features in the controller software rivals serious commercial offerings that I've used (Cisco, Meraki, Aerohive).
