My experience has been "fine" - I don't use anything fancy like dictionary lookup or OCR, I just put epubs/pdfs on it and browse. I find the menu UI pretty good, it's a little unintuitive but there is a short guide that covers everything I need. There is no easy way to browse your library (there is a file browser but I don't like that). Ditto I don't find browsing through a book particularly intuitive, but it has page seeking and you can scroll through pages.

For casual reading, I think it's just fine.

The hospital can be paid less without reducing their margin if they can remove a cost from their balance sheet. It does not make the system cheaper overall, but it means the hospital does not have to bear those costs directly. They may not have to bear them at all, because hospitals are not the only things in the system.

By contrast, how many conversations have you personally had with people working at a company believing a profitable action was firmly unethical, but felt forced to behave that way due to "business realities" or some other whitewashing?

So, pseudo-philosophical mumbo jumbo. There is of course no-one responsible for the ethical framework of the company's actions, because it is a company, and therefore amoral at best and immoral at worst.

If that's not "turning your brain off", what is?
