[doublepost=1473332942][/doublepost]I also agree on the lighting port. With the old 30 pin adapter i personally never had any issues with it. With my iPhone 6 after a years use the whole thing had to be replaced as the lighting port was "opening up", which meant the lighting cable couldn't fit the port therefore charge the phone. So there is a weakness in it. Now we have to rely on the same port to deal with headphone use as well as charging, so it going to get more use per day.
This is a very good point. The single port is going to get a lot of traffic, and is now a single point of failure for charging and headphone connectively. I really think this was a terrible idea by Apple, and it will be solved with wireless charging next year!! I am sure that they will make Qi proprietary like they did with the iWatch so it's not compatible with all the Qi charging pads on the market.
I used to use bluetooth headphones some years ago.. they suck to have to charge all the time, and like we need more radio waves next to our head?
