Just to close out my order history, my iPhone 7 plus Jet Black 128GB was delivered this morning by UPS and is gorgeous as expected. Too early to tell if I can live with the plus sized phone but it's actually not as bad as I expected so early signs are good. It fits in my jeans pocket with just the corner poking out and I can get in and out of my car with it in my pocket no problem. That was one of my main worries and it seems fine.
I've not really had much chance to play with it today as I was busy but the screen is lovely, the camera zoom is nice and the touch ID "button" feel fine to me. The Jet Black texture is definitely much grippier than the satin finish which you can confirm by holding each in your hand and then tilting your hand and seeing which slides off first. It's not even close!
That said, the Jet Black acts a bit like the iPhone 4 and 4s in that it almost imperceptively slides when on fabric surfaces (eg. when lying down with the phone on your chest) and eventually will slide off. This used to happen to me with my iPhone 4 when I put it on the arm of my sofa so watch out for that, especially if you have hard floors like we do now.
I've still not decided if I'm going to use the phone 'naked' (the phone, not me!) or if I'll be getting a case for it. I'm leaning towards going caseless (spell checker changed that to 'careless'

) as it's just so nice to feel and I can live with a few abrasions and will probably buy Applecare+ to cover anything more serious. I really like being able to swipe edge to edge again which you can't easily do with the leather or silicon cases. I also worry that the cases will themselves cause scratches if taking them on and off as I tend to do fairly often.
So, a big thumbs-up to

once again for making a beautiful product and getting it to me ahead of schedule. My original ship date was 26th Sep to 3rd Oct so arriving on Sep 21st is pretty good considering the high demand etc.
Enjoy your purchases guys and gals!
