You have to understand that with each new iPhone release people get excited, get protective of Apple, lose their minds if there is criticism, and reject the idea that Apple is just another company.
I stood in line for the first two iPhones. They were original, innovative, and unlike any other phone. The Apple Store thing was fairly new. Standing in line I ran into friends, and enjoyed the overall experience. With time I started to get tired of waiting in line so I waited for a few months until the hoopla wore down, and then I'd just walk in and pick one up. Nowadays, I seem to skip ever other release. I seem to be skipping each new "S" version. In my opinion the Apple phone has run it's course for the most part. Now it's just tweaking. Granted each new version offers something new, is faster, thinner and a different color. Now we throw in a new way of connecting headphones. Some people love the idea of a new concept, some are resistant. This thread will go on forever.
I am getting used to the idea that people are irrational in my eyes, perfectly sane in their view, and will get excited with every new Apple product. For example I had to laugh at some of the comments when Apple came out with the iPhone SE. It looks just like the iPhone 5. Yet people were all excited claiming they were so happy Apple came out with a new smaller phone. "It's so much easier to hold and use one handed". All this after everyone in essence had been using the same phone. They were then calling for a larger easier to read phone like their competitors. You will prematurely age if you try to figure all this out and rationalize it. I love Apple products. Not all of them but many of them. If there is a better version of something offered by a competitor I will buy it. Since adopting this attitude I have bought a new, better, non-Apple router. Just picked up a Roku Ultra to replace my Apple TV3.
If Apple comes out with a better product I will buy it. But for me I have 6 six pairs of traditional headphones, some are HiFi quality. I may pick up a new iPhone at some point, but not until we see how this plays out. As far as I know Apple is the first to delete the headphone jack. We shall see if this becomes the standard. Then I will decide. Besides I am allergic to dongles.
