I have the 7+ in the flat back, 128mb. Love it, the haptic home button takes a few times to get used to but it's not a deal breaker or anything, I keep reading people are freaking out over it, I think they just have been out of their safe spaces too long.
It's wicked fast and wicked smooth.
Love the screen, even thought only new mac screens have the wide gamut so that's the only way to see the real difference for color in pictures, everything else looks better as well and the 2x zoom is awesome.
This is a terrible picture to take, but this is at night, new moon, no lights on expect what you see, I'm about 50 yards away from that house, this is just a regular picture from my balcony to test night shots.
I'm pretty sure on my 6 that would have just been a black, highly pixelated screen with an incredible amount of noise. It's pretty impressive you can see the wood fencing there at the back of the house.
Oh and the pics are huge, silly me I emailed the large version and it was too big to upload here.
