I think you're overselling the input device argument here. I work all day on a regular computer -- big monitor, mechanical keyboard, mouse of my choice, etc. BUT when I do personal travel, or leave my office, I can do almost anything I want or need to do with my iPad + Magic Keyboard, which includes a trackpad. It's not the lack of, or default positioning of, input choices that make a general computer superior to a tablet for many tasks; it's the whole way the OS works. MacOS, Windows, and (I suppose) most Linux window managers are predicated on having lots of persistent windows you can move around, reference, etc. Tablets and phones assume a fullscreen approach. Modern iOS has the ability to show multiple things at once, some of the time, but it pales next to what you can do on the general purpose OS of your choice. THAT, to me, is the productivity gap. This is NOT to say that I want iOS to change and become more like MacOS in this regard. I think there's a real place for both modes. It just depends on what you need to do (and, to a point, where you need to do it).
