I stumbled on to LaTeX in my undergrad, following my switch to Linux and Emacs. I switched from Open Office, and use it for 2-3 letters per week plus all homework. My favorite thing about it is definitely that it is amenable to version control . Now I usually use Orgmode to transpile to LaTeX (or whatever else I want to transpile to).
