Personally I'd probably not use most of it, just like I haven't used most of the gimmicks Apple has introduced over the last few years, but I just watched the Verge's 10 minute
compressed version of the event and I will say this:
There's plenty of stuff in there that sounds cool that people here would spend page after page defending and promoting if this had been an Apple event. The same goes for the recent Pixel event, where Google did introduce some really neat features I'd actually like to have on my iPhone.
I mean, I don't disagree that 200MP sounds like a marketing gimmick, but let's wait for the first real world tests of the camera before we dismiss it?
