Apple just killed the headphone jack: what's next?

"It really comes down to one word: courage," Apple's Phil Schiller said from the 578 billion-dollar company's presentation stage on Wednesday morning, explaining why Apple is going to render the headphones and stereos of hundreds of millions of customers obsolete. The news, that Apple's iPhone 7 and 7 Plus would remove the 3.5mm jack, an audio standard for over a century , has been rumored for months.
