Wow.. you can finally plug in a USB drive/card reader/camera/whatever... That alone actually takes the iPad a long way towards actually being real/Pro/whatever. I sold my first Gen iPad Pro over this stuff. It was just to painful to do a lot of real world stuff that involved files. Maybe today the experience would be a heck of a lot better.
Clearly many people are using iPads in the real world for all sorts of things and are satisfied with the results. You mean "laptop/desktop like things" which is a reasonable comparison to make, for the small subset of people who want that kind of functionality. But to say that that stuff is "real world" while other uses cases are not is condescending.
It's like the people who say MacBook pros "aren't really designed with pros in mind". I've written over a hundred thousand lines of code for work on MacBook airs and plain old MacBooks which are just great for my particular work flow. Doesn't mean I'm not a pro, any more than it means that people who need a larger machine to run Xcode etc are more pro, or less pro, than I.
I don't mean to harsh on you but I do think this is an important point.
