Sadly the Sailfish ecosystem very much feels like it's on life support at this point. Many of the applications I remember from Meego are still seeing light maintenance, but many others still exist and function, but no longer see maintenance.
Jolla seems to have no interest in markets outside of Europe (I had to use a UK prepaid bank card and vpn to urchase it from the US), so a great many folks who would like to develop for it can't even get ahold of a device without jumping over hurdles.
I'm to use this phone until either the Librem 5 or Pyra ship, but won't hold my breath.
