I think it is the other way around -- almost always a Mac user will be an iOS user, but there are plenty of iPhone users without Macs. At least in the US. iPhones seem to be around 50%-ish of sales in recent years, while Macs are not as popular, somewhere around 15%.
Of course, there are lots of competing estimates for this sort of thing, but the numbers are so far apart that I don't think it matters too much.
Personally, I have an iPhone because I'm completely uninterested in cellphones and just want something that I don't have to think about too much/will be supported for a while. My computers all run Linux, because computers are cool, and fun to tinker with. Maybe someone who grew up in the era where cellphones weren't so useless will have a different perspective, though.
WRT dongles -- I dunno. Some of the popular Macbook models don't have HDMI ports, right? That seems pretty annoying. But my ZenBook lacks a headphone jack! The moral of the story is I guess that OEMs just want to fill our pockets with dongles. Or maybe selling replacement dongles is the solution to the post Moore's law era, since we don't have to replace our PCs anymore.
