The definitive headphone jack post:
If you cannot get on board with the removal of the headphone jack I feel sorry for you. Why would you have 2 "holes" in your phone when you can have one and soon with AirPods and wireless charging there will be none and waterproofness will be so much easier to accomplish.
The audio jack is more than 100 years old - it is time to do something better and more efficient.
There is very limited space in phones because they must be compact enough to carry around, removal of the headphone jack frees up real-estate for new and better technology to come along and fill that void.
There are 2 big arguments that are valid about the removal, but there are VERY SIMPLE fixes for both.
"I can't use the headphones I have now that already use aux." - Yes you can there is an adaptor in the box and there are new headphones that connect directly to the lightning port, if this solution doesn't float your boat, don't buy the phone and don't let the door hit you on the way out.
"I can't charge my phone and listen to music at the same time." - Yes you can for $10 on Amazon you can get a splitter cable lightning to lightning/aux or buy AirPods or ANY other wireless headphone, if these solutions don't tickle your fancy, don't buy the phone and don't let the door hit you on the way out.
Samsung is rumoured to also be removing the headphone jack after mocking Apple publicly about it, once again Apple is ahead of the curve in things that matter the most and being innovative. In 2 years people will wonder how it took Apple so long to remove the headphone jack - just watch.
