Are you maybe also using the web other than Twitter/FB? I've never seen such an abysmal situation regarding browsers. The build-in and the "advanced", which is build on the same engine, should never have seen the daylight. The email client otoh is quite ok. (speaking for the TP)
And none took the effort porting or building something usable.

A system can't live from good taskswitcher and notifications alone. Especially if the "ecosystem" is non-existent, and the community consists to a high degree of joe regulars and script-kids, whom can pull off only a handful of good projects (Wterm, TouchPlayer, Google Maps, f.e.) while not being able to actually fix the OS' shortcomings.

The devices even suck as pure media consumption devices (castrated GStreamer framework, shitty video players f.e.).
