Is R turning into an operating system?

Over the years I convinced my colleagues and IT guys that LaTeX/XeLaTeX is the way forward to produce lots of customer reports with individual data, charts, analysis and text. Success! But of course the operating system in the office is still MS Windows. With my background in Solaris/Linux/Mac OSX I am still a little bit lost in the Windows world, when I have to do such simple tasks as finding and replacing a string in lots of files.
