No, but I can expect modern technology to support universal and ubiquitous standards that has no shortcomings and is super reliable. I can also expect modern technology companies to offer an adequate replacement standard before removing the older standard.
Bluetooth is still unreliable - especially in cars. Ask any dealer service center how many people come in for help with Bluetooth, it's a shockingly high occurrence and I know the service folks at dealers hate it. Moreover, no matter how you slice is, Bluetooth sounds worse; this can be especially apparent in newer cars that have good sound systems.
Lightning headphones are more expensive and incompatible with any other device.
I don't disagree that we are moving towards a more wireless world, but I think Apple would have done better by shipping an iPhone 7 with a headphone port, but still including the lightning earpods and launching the airpods, and transitioning all their Beats headphones to use the W1 chip and offer a Lightning cable option with all wired Beats headphones.
Removing floppy, dvd, serial port, firewire, etc, are all great examples of addition by subtraction. Apple removed something, but had already replaced it with something better. Floppy was replaced with CD, and Apple shipped a computer with a CD drive before removing the Floppy. DVD was replaced with iTunes Store downloads, and the iTunes Store was up and running before Apple removed the DVD drive. Serial port was replaced with USB, but USB was available on Macs before Serial was removed. FireWire was replaced with Thunderbolt, but not before shipping a computer with Thunderbolt. Always replaced with something better in every way, before removing the older thing.
This time Apple is replacing something that was nearly perfect with something more complicated and sometimes of worse quality. It's just subtraction... no addition. I wouldn't mind as much if Apple had done more to promote and release lightning audio accessories and their fancy new W1 chip before making this change, to give the industry some time to put out compatible products.
This is the decision right now:
(1) Are you not ready or able to buy new wireless or lightning headphones to replace whichever ones you love right now?
(2) Are you planning to fly anywhere soon and use in the in-flight entertainment?
(3) Do you have a car without bluetooth (or where bluetooth sucks)?
If you answer yes to any of the above questions, then buying the new iPhone 7 isn't even on the table.
For me, it's: (1) Yes, because the model I love (Bose QC20) doesn't have anything even comparable that is wireless or lightning; (2) Yes, there is high-chance of me flying several times and I want to use the in-flight TV; (3) No, but I prefer aux-in for sound quality, and I do charge my phone while in the car all the time.
