I made it through college without using windows on any of my personal machines, but I did need to access a library or computer lab to take 1 test that needed a specialized web browser for some reason. Other than that, I was actually pleasantly surprised by how easy it was to slip by with a good PDF viewer, libreoffice, and Inkscape.
My degree was in computer engineering, most groups I worked in outside of the engineering department just preferred collaboration through office online or google docs.
