In my car I sometimes need to charge the phone and have it plugged in to the sound system at the same time. Dongle doesn't solve that problem. Very happy with my iPhone SE, not looking forward to getting one without a jack one day. I'll deal with it one way or another, but I can understand the outcry.
Maybe by then a wireless charging solution for cars will be available that is convenient to use.
I like my iPhone SE a lot too. The price and form factor work for me. I donít think Iíll miss the jack by the time I upgrade really. For the times I do like to listen to music out walking around, wireless would be plus.
