Not sure what their source is but I thought I saw it elsewhere too (not that it makes it true!)

There have been two releases that I know of. I've tried them on my note 3 and galaxy tab pro 8.4. The first release seem to work ok but the second seemed to crash a bit too much. Currently, for me, other launchers (like ss launcher) combined with some Xposed modules (like swipe) give a better overall experience. When Android L comes out, my guess is that the gap will widen.

I just got hold of a nexus so I hope to try out sailfish on it in the near future. I actually have a Jolla phone but don't use it as a daily drive. More fun just trying to get Sailfish to work on other hardware.

I kind of wish the N9 OS could be ported to android. That was about the best overall experience for me. Very well thought out.
