I'm still not seeing a convincing argument for the tangible benefits of ditching the 3.5mm audio port.
Other comparisons don't seem to resonate with me. For example, Ditching the Optical drive in machines had tangible benefits in decreased size/weight, more space for storage, increased battery space & life, airflow design enhancements, and removing the drive also meant removing one of the moving parts that needed the most repair/replacing (that most people I know, just attached an external drive instead of replacing anyways)
and there was already well established (and arguably better) alternatives with thumb drives, AirDisk, NAS,external drives that were faster and more capable than what apple was including in their internal drives etc..
Also Apple still offered Optical drive equipped machines for some transition time.
With ditching the 3.5mm port what is tangibly gained? increased hours of battery life? (certainly not with Bluetooth, or lightning headphones that are terminating so you can't charge and listen at the same time)
What is actually held back by keeping the port? (there are already phones thinner, and with water resistance that still have the port, so it's not those)
Decreased costs for customers? (Not in terms of headphones or adapters that have to include extra circuitry, certifications, etc. and the costs will certainly be passed to customers)
It's just that so far we haven't seen any tangible indication of what would actually be gained by ditching the port, and what is actually held back by keeping it. For consumers or technology (since we can already buy lightning headphones, or Bluetooth headphones if we want, the port certainly isn't holding those back.)
Something isn't bad tech just because it is "old", I still use a keyboard and mouse every day both are technologies going back many decades, I still use wheels every day, zippers, Velcro, etc... my point is simply that "old" isn't a reason unto it self to be replaced. (though I will gladly replace my wheels with hover plating when we have it available

)
Someone please help me understand, I genuinely want to know, I'm not trying to be hostile but I just don't get it. for as fervently as some people seem to want it gone, there must be tangible benefits for getting rid of the port and real disadvantages by keeping it right?
