content: Not everyone needs a headphone jack though, so it's not idiotic for a phone to necessarily go without one.  I have used my headphone jack once over the last two phones I owned (GS3 and GS6), and it was to listen to internet radio in my car.  Because of how infrequent I use headphones with my phone, and where it actually gets used, an adapter really isn't an issue for me.  And if I were to buy the iphone and loose the adapter, then I would just wirelessly stream to my car stereo via bluetooth.
