People also complained when Apple removed the optical disk drive. I sure don't miss mine...
Look to the future people.
I've looked to the future. Know what I saw? At least another half century of billions of audio devices of all description continuing to be manufactured with the globally standardized 3.5mm (aka 1/8th") stereo audio connector, or its easily-adapted big brother, the 1/4" stereo audio connector.
I also looked to the past. Know what I saw? At least half a century of billions of extraordinarily long-lasting and high quality audio devices of all description, that still work perfectly and can be easily connected to any device with a globally standardized 3.5mm or 1/4" stereo audio connector, which has been a standard now across the world for decades.
When Apple removed the floppy drive it wasn't a big deal for most people because the floppy format was already dying and being replaced by USB flash drives and email attachments. The same is now happening with the optical drive. Most users in recent years simply never used them now that streaming and cloud storage is becoming the norm. The few people who actually need floppy or optical drives could add them externally with USB.
This is different. There is no consumer advantage or convenience whatsoever in having a music player, be it an iPhone 7 Plus or an iPod shuffle, which is suddenly no longer compatible with billions of standard audio accessories without some dumbass easily-lost proprietary dongle. You are slobbering on Apple's proverbial rosebud if you think it's a good idea for them to abandon a truly standard connector that has no chance of disappearing in any of our lifetimes. Bluetooth is not a proper or reliable solution for every situation either, so don't play that card with me.
Oh, awesome, I can buy an expensive Lightning-equipped pair of headphones, which will only ever be compatible with Apple devices with Lightning connectors. Wait, why would I want that? And if I want to charge my Lightning-equipped device while listening to music on my Lightning-equipped headphones I'll need some kind Lightning splitter dongle that will probably be a different dongle from the one that will let you plug in standard 3.5mm headphones, and it might even require a different dongle to charge while connected to a standard 3.5mm connector, unless they're insane enough to make a single dongle with three connectors hanging off of it (3.5mm stereo, Lightning pass-thru for power plus another Lightning pass-thru for audio?).
No matter how you slice it this it is an insanely idiotic path for Apple to go down, if this rumor turns out to be true.
Now, one last wake-up exercise. Everyone who believes that the Lightning connector will be around for more than a few more years before everyone including Apple moves to a true universal standard power+data connector like USB-C, raise your hand. No, keep it up. If it's you're right hand, tilt your head to the left. If left hand, tilt head right. Now, drop your hand and slap yourself across the face for being a fool. Proprietary connectors come and go. The proprietary Apple Lightning connector will be so long gone it will only be found in museums by the time the 3.5mm audio connector even begins to die out.
And you think people make fun of Apple products for being only for chumps with too much money on their hands now...
