I use the headphone jack on a daily basis on my Macbook and I'd hate to see Apple removing essential ports. I don't even mind compromises provided the Pros outweigh the Cons, but if they truly only have USB-C ports then frankly I'd be inclined to finally switch platforms.
There's less and less reason to stay with Apple now, at least for me. I don't think people should put up with it, vote with your wallets. Why would you want less ports on a Pro product? The future? USB-C is so new at the moment, very few to almost none have native support yet. What monitor could you buy? I can only think of one and it's pricey.
I don't want a computer that relies on adapters, half the tables going to be filled with adapters or wireless items. And I certainly don't want to have to buy new headphones, mouse, keyboard etc.. just to accommodate Apple's silly decisions.
Honestly I think It's getting kinda crazy, Apple is moving in a direction that I'm totally against. It's like Microsoft is coming to it's senses and Apple is the one with issues now
