Perhaps unfairly, it's hard to take physics papers not written in LaTeX seriously. At least within particle physics and astrophysics/cosmology... I don't really read papers from other fields.
Note that, arXiv makes you post LaTeX sources if it detects that it's a LaTeX document, and not everyone remembers to redact perhaps not meant to be public comments :).
