I did, and Word version 2 was an excellent product. WordBasic was incredible. There was even a graphical dialog-builder, so you could invoke dialogs from your macros. I wrote a macro that parsed and re-wrote SQL queries for a Big-6 consulting firm, saving them man-weeks if not months.
I used to work with a guy that used docx files for all his note taking. Basically did all text writing (other than code) in Word. We had Notepad++ at the time as well, so he just preferred Word for some reason.
