I’m using an iPhone 6s right now and this phone does everything I want and then some. The only reason I would upgrade is for bettter battery life or maybe a faster processor. Everything else it does perfectly well for me. So why would I want to replace it with a phone that forces me to use a dongle just to continue using it the way I’ve been doing for years? Especially if that dongle negates every size advantage that not having a jack might add.
As for me not wanting to stay current with tech (as someone above said), it’s because, for me, wireless earphones and dongles are a major step backwards. For you, not having a cable and having batteries might be a feature. For me, having a cable and not having batteries is a feature. I don’t want bulky or expensive dongles.
Anyway, unless Apple decides to cater for people like me again, I’m not going to buy any nore of their devices (and I’m not someone who doesn’t buy Apple anyway, I own multiple Apple devices)
