Well it looks as if Sailfish is an evolution of Harmattan. Not a direct offspring, but a more attractive cousin per say? I don't think we've seen enough to make a judgement. I'm very interested though. I've broken to N9's and am using this abortion of a Lumia until I get a new one. I was going to get the Note 2, but i may just wait until the first Jolla device next year sometime.
