I have a lot of experience tinkering with the Nokia N9 and the Jolla 1, and have written them off as a waste of time. The Nokia N9 is a truly beautiful device, the look, the feel the way it rings, but work on the Meego operating system and apps was sadly chopped off by Nokia managers. I remember having a running tracking app on Meego which worked very well, and without uploading my runs to endomondo. But meego was a total dead end, you could not install android apps on it, could not install symbian apps on it, and if you are just trying to get on with your business and personal life, it might be fun to own an N9 for a few months but it's idiosyncracies and limitations will wear thin after that. So I did try to install sailfish on the N9, but it is not really usable. Then I got a Jolla 1, which is hardware built for sailfish. Remember on a trip to the US was disappointed despite it being a 4G phone that it would not connect at all. Anyway, it is rather buggy anyway, there is the Jolla store with sailfish apps and an android emulator thing which lets you install android apps on it. Actually, was really impressed by something android I put on it and how well it ran. In addition to the Jolla store for native sailfish apps, there is the 'storeman' or 'warehouse' store from
https://openrepos.net/ These apps are more from grass roots programmers which is cool, some only half work but is cool to have an area in the phone where you can test experimental apps.
After that trip to the US years ago where the Jolla 1 did not work, I packed it away and forgot about it, but then a few months ago got it out to see if the OS has moved forward. It now has version 3 of sailfish OS on it, which is the most it can have, and I was rather in disbelief that there is no native matrix client for the sailfish OS. How can it take itself seriously as an open source and privacy focused device..
I remember the early marketing for sailfish, tatooed software developers.. Sailfish was founded by those who lost their jobs at Nokia but were still passionate about the meego project. Still, they have managed to annoy and disappoint their funders, both crowd campaigns and investors! They are somehow just aiming a bit in the wrong direction IMHO, rebels without a cause, possibly even left wing anarchists, who knows. Long story short - don't get excited about sailfish, save yourself the bother. I wish that was not the case but it is buggy and the people who steer it are not thinking quite right.
That being said, I have not tested their latest iteration Sailfish X which requires a Sony device. Maybe they have redeemed themselves..
I have ordered a Pinephone, the first set sold out really quickly. Those kill switches are really cool. The first batch of pinephones sold out really quickly. There is another linux smartphone from Purism on the market but it is a bit too pricey..
