As for the headphone jack, if you think it was a stupid idea to remove it, you should save your vitriol for the "idiots" who copied Apple. Surely it's worse to take what you'd class as an obviously stupid idea and blindly copy it like a brain-dead zombie. At least what Apple did showed actual courage. And yes, I'm using that word entirely un-ironically. I personally think it was courage and they've been proven correct by the rest of the industry.
(Personally I'm glad they got rid of the headphone jack because it prompted me to get a pair of Bose QC35 headphones. Absolutely brilliant. Best headphones I've ever owned, and I've owned some high end ones. Meh. I'll leave the "good sound" at home thanks—when I'm out and about I care far more about blocking out the distractions than maximal audiophool wankery.)
Not to mention media-centric phones without headphone jacks. Remember how services like Apple Music are supposed to be the company's future? Hey, let's make it HARDER for users to consume those services, by removing the audio output and battery life! COURAGE!
