Which is 100% true. And it's also true Dropbox was a great product because it provided this functionality for the vast majority of the population who don't have the time or interest to learn all those tools.
You missed the point. It's usability rather than functionality. I can 100% do all of this but there is no chance I would choose this over OneDrive/Dropbox etc.
Although there are new functionalities from Dropbox -- (easy) online access, apps, preview, on-demand access, (presumably) redundancy on the server etc
