I'm on Windows + iOS (which says a lot about how much tinkering I like to do with tech :D ).

When it comes to ease of setup and general UX polish every open solution leaves a lot to be desired. In the choice between insecure and cumbersome, insecure wins every time. Case in point: gmail is what people want in terms of usability. A more secure solution (such as any pgp solution on standalone mail client) is not really an option.
