I genuinely like the touchbar, and I can see it being something really useful, but its like any early adopter tech, serves little use outside of Apple's stock apps. The huge force touch trackpad is annoying, I have to move my whole arm to avoid touching my pinky to it when switching between typing and mousing. On the flip side, The new SSD is blazing fast. I can fly on the shallow keyboard. For me, it boils down to this: Is Apple going to solve my top 5 issues via software updates in the upcoming months (which I think they can), or are they going to reverse course in 2017 and make the machine they should have released at last year's reveal. Rumor of "significant redesign" is highly concerning.
I too loved the 6S, but the 7 is really really fast. I really griped about the headphone jack (still do), but I've heard AirPods are excellent (at least according to Marco and crew on ATP) and have a pair on backorder.
