Where I live we have long stretches of cold weather and wireless earbuds of any kind stop working after a few minutes.CarPlay wasn’t mentioned, but that’s probably one of the most important features people would lose.
I just purchased a new vehicle that doesn’t have wireless CarPlay so the chance of me buying a portless phone is pretty well zero.
I have to use wired earbuds when I head out for my daily walks. A portless phone would be the end of listening to podcasts while walking.
