With all the rumors, leaks, however you want to characterize them, about the iPhone 7 being a minor tweak of the 6S a couple of questions come to mind:
1) Would Apple spend much time on this at a typical fall iOS Event? I'm thinking, no, not much to hype and not look silly. So then, do you think there will even be separate iOS and Mac events or just one big fall event for presumably MBP, iMac, iPad Pro 13", maybe AW? Maybe AppleTV?
2) With the iPhone 7 apparently just a hair's difference from the 6S -- A10 processor, better camera maybe, but no headphone jack -- do you think Apple will just EOL the 6s completely and keep the 6, 6+ as the mid line just to ensure there is enough feature room between the the two price levels? Personally if my choice was the 6S or 7 I'd pocket the extra $100+ and take the 7. But in reality I'll just keep my 6 until the 8. Still curious though how everyone thinks this will shake out.
