Nope. It's internal design. Internal space. The less things taking that space, the better you can make the phone. Give you a quick example:
Let's say new battery tech came out and you could get the same battery life out of a battery that was physically 1/2 the size. You could then do any of the following, including innumerable other things that I'm not listing:
•Greatly enhance the speaker quality
•Add a 3rd or 4th camera sensor to the rear of the device
•Add numerous new sensors to the rear and face of the device, for AR capabilities
I can't make excuses for Apple's lack of innovation. They simply removed the headphone jack without anything better to take its place. It takes courage to do that. Other companies make better looking products.
