The biggie for me is books I have written and maintain that were published in pdf from both Word and PowerPoint, probably totalling 2400pp (example here and here). Converting whatever foibles they might exhibit in the tranistion to their Linux 'equivalents' is not only a learning problem, it is a huge logistical problem.

Not sure I understand—PDF is PDF whether it’s in Windows or Linux.

That doesn’t represent the vast number of computer users.

You need to keep your proprietary machines unless you want to invest a lot of time in making the transition (it will work better if you do transition to linux)
