I might be missing something, but what does this do that an app like AnyDesk doesn't? Is there something inherently better about remoting in with dedicated hardware rather than using any of the free and widely available software solutions? I can see where this would make sense for low powered machines that can't easily encode video at high speeds / low latency, but I struggle to see the sense of this in a context where I actually want video output (a powerful workstation) rather than just SSH.

It doesn’t require the OS on the target hardware to be running, and no other software can get in the way. It can also connect via a separate network than the one the computer is on (if any).

it’s useful to be able to get into the bios for remote support situations of critical servers, I guess

I believe the primary use-case for devices like this is debugging "Why isn't this server rebooting?" without driving to the datacenter. Good luck figuring that out with AnyDesk or SSH.

Work when the network config on that particular computer is down/borked.

or allow you to do a fresh OS install.
