That adapter forces one to choose to listen to music or charge a phone, which is very problematic when using GPS, as it's very battery intensive, especially as the phone is often in direct sunlight.

>Time moves on, should they also have not gotten rid of the 30 pin adapter?

Apple is still releasing new hardware with a 3.5mm port! The port is far from outdated. Again, both wireless and wired audio coexisted nicely on the iPhone, this is a problem of their own doing, and they've made the experience objectively worse.

We're just going to have to agree to disagree.

Apple is also releasing new hardware with multiple USB-C ports and an SD card reader. Does that mean it should also release an iPhone with all of those features?

iPhone never had SD card support, so that's a non-sequitur [Edit: Because we're talking about unnecessarily deprecated features, not new ones]. And yes, iPhone with USB-C support would be incredibly well received! Time to ditch the Lightning port asap.

It’s not a non sequitur that Apple should have kept a headphone Jack on the iPhone because it is on other devices?

They did have 5 generations of phones with 30 pin adapters.
