I've been firmly on the fence about everything we've heard about the iPhone 7. As a musician, I place a fairly high priority on being unencumbered in listening to material on my phone. It is looking like it's increasingly likely that the use of the lightning port for headphones will not be mated to a method of charging by some other non-lightning means.
That's simply infuriating to me. And - get this - it's actually a deal breaker. I know, so many talk the talk about abandoning the iPhone, but I am willing to walk the walk. I will wait until the iPhone 7's official announcement before finalizing my decision, but since my contract's expiring this fall, I'm fully anticipating purchasing a Nexus device instead of a new iPhone. Further, the 6P is $0 from my phone provider; I'll save a couple of hundred bucks in the process.
In no way does the inconvenience of migrating some of my iCloud information to Google's cloud suite outweigh the inconvenience of not having the 3.5mm headphone jack on my phone.
Shame on you, Apple! While you may think the elimination of the 3.5mm jack is innovation or progress, I only see a reversion to the pre-smartphone era of awful proprietary earbuds bundled with flip phones. Except you could charge and listen simultaneously with those.
