Beyond the secure enclave, if the haptic home button is anything like the new trackpads, it'll be an amazing feature. One less moving part to break. And the cameras...wow. Finally decent depth of field on the camera that's always in my pocket.
"Another thing I tried: the new home button, which uses a "taptic engine" to give you physical feedback when you press it — it's pressure sensitive too, so it can tell if you really mean to press it or just tap it. And it's awful. On a MacBook trackpad, you get this uncanny feeling that you're actually hitting a button. On the iPhone, the whole bottom of the phone just sort of "kicks." It's not bad haptics like you remember, with weird vibration, it's just a new kind of bad haptics. It doesn't feel like a button at all. It's a bummer."

Recently I upgraded to the Samsung Galaxy S7. It was about $400 and it has an incredible camera; far better than my old iPhone 5s, and it looks substantially better than the iPhone 6/6s photos I have seen. Plus, it has a headphone jack, microSD support (so nice to be able to upgrade), and a really beautiful screen. Yes, Samsung installed some bloatware but some of it is actually useful (their UI for toggling radios is quite good) Android Kit-Kat is solid. To me, this was Android's first reasonable phone.
iPhone users will always prefer iPhones for something.
> Android Kit-Kat is solid
The S7 doesn't ship with Kit-Kat, does it? I think it has always shipped with at least Marshmallow
I take your meaning though, and that there is reason to hope it will work better than the mechanical button. And even if the feedback were to fail, the button might keep working.
