What’s the percentage of people that use the iPad Pro for that tho? The majority don’t, Apple will probably go with the majority. No one knows for sure but I wouldn’t be surprised if they do remove it from the iPad Pro as well.
No one has this metric because nobody controls the standard to analys it.
However, for thoe who say it's Obsolete" because the iPhone dropped it don't understand how ubiquitous the 3.5mm jack is. it's quite literally the most used analogue audio jack in the world because there's been nothing suitable to replace it.
I'm not discounting wireless for many uses, but wireless doesn't fit all use cases.
the 3.5mm jack on the other hand is the standard audio plug accross hundreds of different product categories and technologies and is a universal jack meant to bridge the audio gap between anything and everything that requires an analogue signal.
it's one thing to say "well, i'm just a consumer and I dont need it", but shows a significant lack of understanding of the actual purpose.
This further also doesn't take into account there was no technical reason for it. all the ones Apple claimed are easily debunked.
Also removing the headphone jack removes choice and forces to either use an adapter or wireless. Having the jack in the device provides choice to use either universally accepted wired analogue or wireless should they chose.
removing it from the iPad Pro, which they aim at creative professional, many of which could very well be in audio production, is assanine and further pushing towards revenue control versus actual user wishes.
all the reasons claimed by people, especially on the forum why removing the jack was necessary have been debunked. the 3.5mm can be waterproof and has been capable of it for many years before smart phones. The space that used it was not occupied by anything that had to be there (the pressure sensor itself that is claimed is not actually there, just a rubber gromit. one tht no other smartphone vendor seems to need for the same sensors. In fact, there was even some nutjob who managed to install a jack in there. it's not for thinness, because Apple themselves managed to fit a 3.5mm jack in an even thinner iPod Touch years before. So either Apple's engineers became suddenly so incompetent that they couldn't figure this out while everyone else did, or there's another overriding reason. And that's easy to spot. Profit. Apple cannot profit from the 3.5mm jack because there are thousands of options out there from the open standard. With Lightning as the only plug, they profit from the MFi program licensing, and they can direct their users to get AirPods or Beats at high markups for bluetooth compatibility (which there are far fewer devices compared to wired)
as mentione by the poster above, comparing the 3.5mm headphone jack to floppy, cd etc is also assanine as it ignores the fact that when Apple dropped those other products, there were existing, faster, better, larger products that directly replaced the functionality 100%. The same cannot be said for wireless headphones over wired. both have pros and cons and they're more companion products than replacement products.
