I remember getting older and my mom being annoyed that Wordperfect seemed to be on it's way out and how much more awful Word was
I supported WordPerfect for various law practices in the courts around Chancery Lane in London well into the MS Office era.
The main reason was not templates; it was the word-count function.
MS Word has a very odd implementation of features like headers and footers, footnotes, tables of contents etc. It considers them separate areas of the document, and so when you do a word count, they are not included.
For authors who are paid by the book, this isn't very important. For journalists, who aren't paid for headers and footers, only raw ASCII text excluding such things, it's almost good.
But for lawyers, who are paid a lot of money -- far more than journos or authors -- for every single word, it matters a lot. WordPerfect counts every damned word, wherever it is, whatever region of the document it's in -- so they get paid for all the words the client received.
This could well be a difference of thousands of pounds/dollars/euros/whatever.
For that, a single copy of WordPerfect at £150-£250 could well pay for itself by the first document you sent out.
I used to have an academic version of Word Perfect 5.1 that worked like the commercial version only in printing out it would print asterisks on the printout. It was free and good for editing.
