iPhone 7 included adapter rate: 100%.
If a phone blowing up is not something to be concerned with (ignoring all the Airlines and government departments telling people to turn them off while flying), then a removed audio port shouldn't even factor into your consciousness when you consider that they give you the adapter for free.

In the world of consumer electronics, 50 years is ancient.
At the end of the day the way the 3.5mm jack is used in 2016 is the ultimate hack-on-a-hack-on-a-hack. The plugs are all the same size, but they could have anywhere from 2 to 5 contact points, depending on device type/manufacturer.
It worked for a while, but at some point you have to move on, and someone has to be the first to move. As I said in another comment, Apple has always been ahead of the pack when it comes to adopting new technology and dropping legacy technology.
> Electric motor is over 180 years old, and that's not ancient. It's not ancient if it's used everywhere. If it's used everywhere, it's called modern
No, if its used everywhere its called "popular" or "ubiquitous".
An electric motor can be modern, if it's a new/recent design. That doesn't make all electric motors modern.
