That's true and a fair point.
Although I imagine many aspects to be the same for many general needs (while clearly not for very specific needs). Ideally, those which aren't (such as, perhaps, the monitor) for said general needs could offer multiple choices.
I wanted to be inclusive by saying "productivity" since at this point I'd be open for literally anything that is purposely designed with those general goals in mind — whatever the professional pursuit. It may still be superior for my specific needs compared to all the bells and whistles I keep seeing.
If I'm a writer, I will need very different things than a video editor or software developer to be productive.
