Sure, half a billion people have accepted the elimination of the port, but how many sales haven't occurred because the port doesn't exist? We'll never know, but I personally have reduced my purchases of Apple devices because of this. So there's at least a few. Also, no one has asked me about my satisfaction with Apple devices. I'm skeptical about the numbers that come out. And even if they are actually that good, most people probably have to convince themselves they love the device because they just spent a huge amount of money on it. This is a well-known psychological phenomenon, as I understand it.
Anyway, tangled cords aren't an issue. Just tie the bundled cord in a knot and you are good to go.
"Tangled cords aren't an issue." You just lost everybody with that comment. It's clear you haven't tried wireless or you wouldn't make that comment. I'd just encourage you to try a nice wireless headset, sales show most people have gone wireless who purchase headphones.
You're skeptical of the satisfaction polls because you are only focused on your situation. Remember that most people just use the included earbuds, so they could care less what's at the end of the cord when they plug it in. The people who do have some sort of legacy set they want to use, just took the two seconds to plug the free adapter onto the end and never thought about it again. The large number of people who have switched to wireless, never gave it a thought. So, yes are there a tiny number of people who haven't switched to wireless, or who use something other than the included earbuds, or who didn't simply put on the free adapter and never think about it again? Sure, but that tiny number is so small it isn't even measurable when compared to the probably a billion people who fit in one the first three categories.
