Since this update I am mostly very happy with my Jolla. I have only two serious problems remaining:

1. No 3G possible in North America. Radio doesn't cover enough bands. OK, so that's a hardware issue. Not expecting a software solution.
2. Calendar is still useless for me. This is my biggest problem. Sailfish helpfully offsets all my events by 8 hours, so that a 7pm appointment starts at 11am instead; I don't receive notifications, and I have to dig into the Calendar app with its lousy UI and non-existent configurability to see my agenda.

Otherwise mostly good. Occasional green LED flickering and 30 seconds of blank screen, but maybe that's a low memory condition. Apart from the Calendar, which is still disastrous, I agree with pycage that Sailfish is now well ahead of Harmattan. The browser improvement (not loading the last tab) is significant, too.
