I've been a linux fanboy since 1998 (Mandrake, KDE, lots of bugs ) and as Sailfish basically is the only true (as in a normal linux desktop distro) mobile linux os what's there not to like? Tizen seems to be some Samsung in-house monstrosity and Ubuntu I wouldn't even call normal linux anymore with all their in-house crap, especially Mir and Upstart. So for me Sailfish is the clear choice. Wayland + systemd + Qt = instant success -> road to the future
