Wine/Proton gets better every day though.
Their office buys their stuff from a supplier which ships them a Windows box with all the batteries included.
That's why doctors in my country still prefer legacy physical pen and paperwork, versus interactions with the modern digitized equivalents which are universally hated because they're not designed by doctors but by some consultancy who won the government tender.
Adding dealing with an unfamiliar OS and Wine on top of that is not the slam dunk you think it is.
The average user doesn't want (and shouldn't need) to understand technical stuff like file formats (JPEG vs. PNG), the data load of video streaming, what a "driver" is, etc. Forcing them to grapple with these concepts is a fundamental design failure, but I think it’s a difficult pill to swallow for nerds to accept that others just don’t care about these things.
This is why companies like Apple have been so successful: they don't just simplify the interface, they abstract away the complex, technical reality into a language and experience that feels intuitive and friendly for the users.
[EDIT] The core problem, in case the example didn't make it clear, is that these things interrupt a workflow they use often, and are accustomed to having always work the same way, and do so in service, usually, of showing them a bunch of stuff they don't give a fuck about and didn't really need to know. Even the ones that block interaction to highlight new features are really bad—OK, that's nice, but I'm trying to do the thing I always do with this and you're getting in my way, making my program temporarily behave and look weird and confusing, et c.
She has no conceptual understanding of what’s an app and a webpage and why they’re treated differently, she just kinda accepted she uses something called Firefox to do a search and some icon in the phone that has the exact name of the other app she wants to use. She never understood (or cared) what it means to “close” an app if she already does that when she presses home or back, no matter how much I try to explain.
When you think about it, it’s all very confusing for them, and since people making these things already understand them well, they make stuff assuming the users will understand the whole thing as well as they themselves do.
No other buttons (visible on the face, anyway) to confuse it for. It's right in comfortable reach of the thumb. "Which button do I push again? Oh right, there's only one."
(I also think going to "swipe up to unlock" instead of the brilliant slider they had before was a big mistake, as far as reducing the level of comfort for the median user)
But your POS system where you enter in orders? That's Linux. And guess what - it just works, it chugs along and does its thing.
There's no reason that doctors offices couldn't use software that utilizes Linux. And to pretend that windows is low maintenance? Tsk tsk, windows is a time bomb.
It is possible for somebody to make this into a workable bundle targeting specific professions/environments. A doctor would not care if double clicking X icon open an app through wine or not.
