Medical stuff is not comparable to OS that you use on a daily basis. Everything just boils down that Windows was pre installed on such a huge amount of machines that “you have to be tech savvy” or whatever to use Linux. And the fact that no one wants to install anything that wasn’t installed the first time, makes it that much harder to switch to Linux. But I believe that we all are slowly spreading the word of Linux more and more with each year. We definitely will have a year of Linux for sure (eventually).
