Agreed. Removing obsolete features is advancing. There was a time to remove floppy drives and such. And it would be time to remove the headphone jack if there were a replacement that was at least as good.
Wireless headphones suck. They're expensive, inconvenient, and don't work with most of the things I want to use headphones with.
The parent means that you must deal with advancing technology rather than clinging to the past.
