I have very bad experience. Today something went wrong with touch screen. It ignored touches. I could not unlock for 10 minutes. I couldn't scroll. Touch screen worked in recovery good. So i did reinstall wiped:
dalvik, system, data, cache and installed latest. It worked good.

It's highly unreliable system. If you need GPS quickly you can't rely on SFOS, If you need to send some files via BT you can't rely, If you want wifi tethering you can't rely. Android just works. Sadly this is what it is. Hack even slimport does not work. Other then this all the fancy linux stuff is nice to have on a phone. But as i said all these things i mentioned earlier are not relible for daily use. You should have dual boot with android.
