I remember back when I was overseas with my students and tasked with updating our school blog, I used my iPad for this. It was a breeze using the Wordpress app, typing a few quick paragraphs of what the students were doing at any one time, taking a few photographs of them with my iPad 3's camera, then posting directly to the blog. Doing this multiple times a day was a breeze and it meant having one less task to worry about at the end of the day when I returned to my hotel room.
If the iPad had run macOS back then, I would probably have a harder time fiddling with the desktop web interface in safari, and the process would have been a lot more cumbersome. This was why I was comfortable leaving my laptop at home and travelling with only my iPad. Because I knew that the combination of long battery life, portability, ease of use and inbuilt cellular would meet my needs in a way that a PC never could.
This is one thing I wish a spotlight could have been shone on more. While I am sure there are many people who ultimately gave up on the iPad because it didn't run macOS, I am willing to bet that there are just as many, if not more, people who are able to get meaningful work done on their tablets because of iPadOS. This doesn't make it better or worse than a conventional laptop, just different.
