Picked up a SIM free Jet Black 7 Plus yesterday. Been using a 6 for the last two years. Not sure I am crazy about the extra size yet in daily use. Really wanted it for the camera and can see how the larger screen real estate can be useful but not sure I like just how big it is to hold in one hand. The other strange thing is 3d touch -- I guess once I figure out what has 3d touch functions that are useful it will be a real game changer, but right now it seems I am more only engaging it on accident.
Also for the poster a few above with the video on the 32GB write speed, that is a standard function of SSDs. Nothing to see there.
Finally, I know there is some banter on Intel vs Qualcomm modems. I believe all the SIM free versions come with the Qualcomm chip, although I have not tried to confirm that, and I can say this thing is blazingly fast. I got 78Mbps down on ATT in a building.
