My understanding/impression was that the phone was basicly just a promo for the Sailfish OS, which they hoped would get some the real manufacturers interested on the platform. There haven't been any takers, so its been a major failure in that sense.

Now for my personal use its been pretty good. Lack of the promised 4G was a turn down for me, until the support was added. Now my only big gripe is the camera, which is super bad and not worth using. Other than that I'm propably too happy with it in the sense that I would not upgrade to a new Jolla phone, unless it had much, much and then some more much more better camera.
