I've had WordStar 7 installed on my computers (DOS, win & Linux) since it came out... it's still there on my win & Linux systems and runs fine in DOXBox.
But then I started with WordStar 3.0 (or maybe that was 3.3) on CP/M (a Kaypro II). It wasn't my first word processor but it was the first I used for an extended period of time. I still have a bunch of old files created with WordStar which is one of the reasons for keeping it alive on my current system.
This was a fully functional and (for me) easy to use word processor that ran well in under 64KB of memory. When I finally made the move to DOS (starting around v0.9) I kept using WordStar because it just worked and continued to be easy to use. While I started using Windows with v1.0 I'm pretty sure I didn't make the move to WordPerfect until the early 90's. I recall doing a research paper in WordPerfect in '94, so for sure by then.
I've used a fair number of different word processors over the years but have most of my word processing files in WordStar, WordPerfect, Word and now, Open Document formats.
I didn't care for Word at all in the early years but was forced into using it as it gained predominance with later windows versions. I still avoid it whenever possible. I currently use the LibreOffice suite of tools on both my win & Linux systems. But that's just personal preference.... as always, use what works best for you 8^)
