Re: use case?
There are tens of thousands of desktops used by back-office staff throughout the organization, many of which only need a web browser, office software and email. Anything that doesn't need client apps could potentially run Linux. Admittedly this doesn't mean much for hospital desktops because of the client software on them.
The day 1 goal isn't to kill off license fees though, it's to take the low hanging fruit and reduce Windows dependence over time. When Linux is an option platform agnosticism becomes a selling point, and that'll naturally push down the number of desktops needing Windows over the years.
