Perhaps not for celebration, but for giving attention so that they are not removed by someone thinking "No-one asks for headphone jacks today". It's easy to come to the conclusion that this is the direction we're moving towards, now that more and more phones come without it.
Phones and laptops are quite different in terms of form factor, use case case and therefore demand and limitation. I think the headphone jack is safe for now.
Headphones have been removed from iPad Pro, even though there is ample room in the case and an entire ecosystem of accessories which rely on the headphone jack.
So you believe that a reviewer or perhaps a random internet commenter making a statement for or against a feature such as a headphone socket "gives attention" which is picked up by a company as it works on the spec for subsequent models? How would that work? How would you know whether the person was going to buy one anyway, or wasn't an idiot - what if you get some people who like it and some who don't? Wouldn't you just stick with the status quo, or talk to people who know what they're talking about?
