pros

* swipeui pissing on WP, ANdroid and IOS
* most open platform
* easy and fun make apps with qtcreator qt/qml and/or python
* webkit browser, however the internal browser has not much functionallity but I use it daily. There is a Firefox app in the store but firefox is bloated piece of **** on N9.
* smother than many android phones even this days.
* easy to root.

cons:

* not 10000000 apps
* if you depend on some crap bank who needs an app to login it will not work on n9: switch bank ASAP and let the *** holes know there is something called html5 and https == no need for ****ing bank apps
* nor instagram or whasapp
