Anyway I was interested... do you have useful X running on localhost?

Can live without GPS, but would prefer not to. But audio, audio is mandatory :-). Ah, thanks for the pointer. Built-in battery is very bad for debugging, and very bad when PM is not quite finished. But I remember droid4 was something that disqualified it for European use. Aha, LTE @ 700MHz, which is not available here. Hmm, but GSM/UMTS works in v4.12 according to the table, so that's not too bad. Does ofonod support the modems in an useful way? Is GSM connected directly to the audio, or does it need real-time task, similar to N900? It looks like nice machine. OTOH N950 looks like a nice machine, too, and N900 is actually nicer because of the resistive touch, battery, and friendly bootloader... > > Biggest problem I have now is poor quality of audio calls...
