I'm using Sailfish OS on an Xperia X since when it became available. My main reason to migrate from Android was "battery life" which was confirmed (battery now lasts ~5 days instead of the usual 2-3), but the OS has a lot of small and bigger bugs (e.g. carrier selection, 2G/3G/4G priority, stuck data comm for Android apps) and missing features (notoriously: tethering/wlan access point, bluetooth) that do not currently make it a valid alternative for a normal user if compared to the other operating systems. Version 2.1.4 beta is available (https://blog.jolla.com/sailfish-os-2-1-4-now-available-early...) which might fix many bugs and deliver some key features, but the date for the final release has not been published (and I'm too scared to brick my phone by installing the beta).

What does the OS natively support? Does it have SMS, email, and a browser? Maps?

* SMS - yes

* Email - yes

* Browser - yes -- the official one browser is based on [an outdated] Gecko engine. Unofficial browsers based on QtWebkit.

* Maps - yes -- the official solution these days is HERE Maps (this requires Android support which is available on Jolla-supported devices). There are several other Map solutions available through OpenRepos (a popular 3rd party repository for Maemo/Meego/SailfishOS software).

While the app ecosystem can in no way compete with the number of apps available in Android or iOS -- if you use your mobile for web-browsing, music, podcasts, weather, timers, etc. it's sufficient.

The official browser is actually Webkit based. I believe Maemo was the last OS in that lineage to use a Gecko browser (microB).

The official browser for SailfishOS is Gecko-based. The SailfishOS browser source code is FOSS, so we can see for ourselves, from https://github.com/sailfishos/sailfish-browser :

> Sailfish Browser uses Sailfish Silica Qt components for the browser chrome and gecko engine with embedlite Qt5 binding.
