See, the thing is, you're reading that I actually need .docx, which I haven't actually said anywhere. I do fine with PDF. I don't quite know who you're arguing with to be honest. What I was stating is that using a freely available open document format would be better overall, since I happen to know for a fact that unemployment offices here are running LibreOffice. I also happen to know that businesses usually are running MS Office, because of concerns they have about software support (or because that's just what their XP machines came with in 2001). Furthermore, I know that a lot of older people, who were let go in the height of the financial crisis, have little to no experience with computers and do not know how to use "Print to PDF".
But mate, cheers for the MS Office sales pitch.
