iPhone is kinda becoming more of a cluster**** with each rumor that drops here, hope they aren't all true.
So you will need an adapter to be able to use your old headphones, may or may not be able to charge while doing so.
The home button might be going away, and/or Touch ID is being separated from home button.
iPhone will be thinner, probably have an even smaller battery.
Camera will continue to protrude and/or have a really weird/ugly dual lens setup (That one rumor where it's one unified, wide piece of glass on the back corner is horrifying)
Just... why? For more thinness and waterproofing? Waterproofing is pretty sick but with all these weird compromises I dunno..
I think it would be cool if they somehow implemented Touch ID into the sleep/wake button if they separate Touch ID from the Home Button, I like that press a button and hold it there, *bam* phone is unlocked kind of thing. I doubt that would be viable at all considering how skinny that button will be though since Apple is still chasing after thinness...
These iPhone 7 rumors are scaring me, lemme tell you what. In 2014 I was just scared of the design but I could live with the rest. Now it's getting down to the fundamentals.
