Bluetooth was a step sideways. I like not having my cable get stuck under my chair wheels but holy fuck its annoying to use when you have multiple devices.

What's your source for the reason iPhone sales are dropping?

When you buy into Apple you are supposed to follow the trend. It has been the case since the earliest Macs. So it is not surprising that Apple followers simply do what Apple tells them to do and switch to wireless. I don't like it but it has value. Apple products tend to work quite well when used as intended.

As for sales dropping, smartphone sales do drop. Or at least, the upgrade cycles are becoming longer. It is mostly because phones are becoming "good enough" for many years, but the removal of the headphone jack may have played a tiny part.

We'll just have to agree to disagree, then, because I find that there are zero advantages to Bluetooth in this case. I mean, wireless would be nice in an ideal world where there are no disadvantages, but for me, they are so hefty that it's never worth it.

It's just silly to claim bluetooth is better than the headphone jack. There are lots of reasons people use headphone jacks less. I can't buy a phone one with one, cause I want a recent better spec phone.

This was done with a replacement on hand which was more functional, more reliable, and easier to use. BT is not any of these things.

I mean, I guess... Apple is always early when it comes to killing stuff. But as late as 2016 you could still buy a new MacBook Pro with a DVD drive.
