I'd say the one feature that is game changing for both Jolla and Ubuntu Phone is being able to run it as a desktop device as well as a phone. If the hardware supported USB Type C, there'd be no question that this would be my next phone, even if the desktop functionality wasn't supported at launch it would be a clear statement of intention.
The idea is cool but the computers and smart phones are so cheap everyone has somekind of computer (or access to one) + smart phone. This would've awesome in the mid-2000s, though ;-)
+ Haven't seen a device that really solves different usage patters of mobile phone and desktop in the same UI. If you're going suggest Windows 8-10, I'm sorry to break it to you but they failed miserably.
I don't own a x86 PC, all I have access to are work computers and my smartphone. This is partly out of choice, I want to keep my possessions to a minimum.
As for your other points, I would suggest that previous attempts have failed because they were clunky, with USB Type C the potential is there for a much better user experience.

You're treating your own opinion like a breaking news story. Nice try, but it doesn't give it any extra weight.
