One great benefit that she doesn't touch on is LaTeX makes for a great on-ramp to generating resumes programmatically. I like to use different emails for different services (service@mydomain.com), especially when data is being hoovered into HR systems. Building a pdf at the command line made it easy to create a one-line command (via makefile) that generates a small png with the desired email and insert it into the resume with 0 effort or fuss.
