Got it today
First impressions:
* Very good display, even if the greens are maybe to flashy.
* Quite heavy (!), compared to my 6S
* FaceID is great (I cannot use touch ID)
* I got the white version, and the mirror-like edges will be heavily scratched in a few months
* iOS11 is not optimised for this phone, and this is the most annoying part. It shows a lack of attention for details, as the huge space below the keyboard, the wifi symbol going from right to left when swiping down the right menu, and plenty of other small but annoying details.
