Generally, the advisor rules. Yet, the advisor may learn from the student, especially if the student is wise often to show the benefits. And the issue depends on the purpose: to write paper, to prepare slides and posters, for a thesis? The amount of collaborative work varies with the topic.
Some benefits of LaTeX are nice-looking formulas, great non-standard or forein characters, macros, easiness of collaboration with versioning systems (svn, cvs). So, depending on your field, you might first check whether LaTeX is of help in your domain.
Now with recent pdf editors, it is becoming much easier to comment on a document, and the text editing is quite simple. So now, when I collaborate with non-LaTeX users, I take charge of the editing, offer "input-like" spaces for their parts written in Word. I generally convince them with the quality of the reference section.
Recently, I have been using interesting LaTeX packages, like \usepackage[draft]{changes}
or todonotes
. The first one is great at showing edits, replacements, additions. And just by changing it to \usepackage[final]{changes}
, you get your final text. The second one is fantastic to show, in the document, what is left to do, what is done, and is great for an advisor who see the work in progress. Such packages can convince others that you definitely know what your are doing, with method, and leave you in charge.
So, if you have some free space, my advice would be to stickk to LaTeX, and if you can share the directory with your advisor, he can comment on the .tex and on the .pdf
