Why? LaTeX is good at what it does, and there are predefined templates for high quality resumes in various layouts (for example see [1] and [2]). I've written more using LaTeX than Word, so it's easier for me (and others I presume) to produce good results for out of the ordinary documents, like a resume, in LaTeX.
