Siri is definitely worth using now, even if it remains still a work-in-progress/needs continued refinement. It can surprise you in good ways, but it isn't consistently good yet.
The keyboard remains unfixed, as is tradition. The same issues they've "fixed" like three or four releases now, seemingly are identically broken, and I'm lost faith they CAN fix it.
The iOS Keyboard and Search on Windows, are like the perpetually broken things that both companies have "fixed" every year for the last ten+ years and yet... It is almost farcical as this point.
