Wikipedia:Articles for deletion/List of PDF software
I came across this article this evening and found it quite useful, so perhaps this is something of an  comment. However, while it certainly isn't a perfect article, it does provide more information than would a category or template in terms of descriptions of what software does and sub-categorisation by operating system
