I know plenty of professionals who work wonders with MS Office and who love working with it. Calling them all "unexperienced users" strikes me as pretty opinionated. Just because I would rather solve the task with R instead of Excel doesn't make me a more experienced user, it simply makes me an experienced open-source user rather than an experienced Microsoft user.
