Looks just awful. Looks like somebody had just printed a picture of a screen and then started to draw this picture like "let's put this action here" without even thinking how usable it'd be. In Roppola's slides there is good guidelines on what actions are most important in mobile OS and what kind of swipes are easy to do, with both hands and so. Jolla's final concept isn't exactly as innovative, but still usable on both hands. Those swipes presented in that Purism post are just unreachable and stupid. Like a desperate need of being different, just because of being different. I hope they realize it themselves before it is too late.
