Let's say Apple comes out with a phone with a perfect folding screen, a battery that holds a charge for a month, perfect offline speech recognition, and it costs $100. I still wouldn't buy it if it didn't have a headphone jack, because I'd consider it a bad design. Does that make me stupid? Perhaps. But as an engineer I'd find such a phone insulting: There's no valid engineering reason not to include a headphone jack. The only reason is for Apple to thumb its nose at people who actually care about good design by saying "We're Apple. See what we can get away with?"

It would be like Mercedes suddenly deciding cars didn't need air conditioners any more and refusing to build cars with that option. "We're Mercedes. We know best. You don't need an A/C. Open the window if you're too warm."

The whole premise just sounds insulting, and if it happened you'd never buy a Mercedes again.
