There are a couple interesting-sounding claims made here but there is basically no detail to be found, which strikes me as odd at best and suspicious at worst.

The OS sounds like bluefin-dx, but I'm struggling to figure out who they're marketing to here. Seems like a small market that System76 already owns.

I was confused by the command symbols, since most Linux distros use the ctrl/alt/super terms. But they have some hardware too with integrated keyboard (do any other desktop computers do that anymore?). The custom keyboard layout is both interesting and kinda awful (biggest escape key I've ever seen).

Man, thats a confusing setup for what this is, of which "Workbench" is a reduced desktop environment on some (custom?) linux distribution. All of which runs on the Caligra "developer terminal" (viewable on the home page https://caligra.com/ ) which, from the single top-down photo they provide, looks like a slightly more modern Commodore 64.
