At a local hospital the radiologists have been all Mac for a long long time. They refused to give it up and resisted all attempts to get them to switch. So it doesn’t surprise me at all.

Interesting, I would've guessed that they would've forcibly been on Windows since time immemorial.

Entirely unsurprised that someone would refuse to give up their workflow, though! I've rarely found a user with specific needs who wants to change literally anything else about their system, since what they have works for them.
