engadget also complains about the UX, but they are known to be fandroids, so...

Personally, it took me 5 minutes (yes, 5) to get used to the N9 and I could never go back. In fact, I keep trying to wake up my iPhone with a double tap. I estimate that Jolla will be another 5 minutes to get used to. The question is whether I could still go back to the N9 seemlessly ;-)

EDIT: engadget is still trying to upload their video. They are probably using an S3 or something or other ;-)
