An iPhone 7 that's a greatest mash-up of the 4S and 5S design? Shut the F up and take my money.
I still have my old 4, and whatever they used for the glass on the front gives such better image quality than what they use now. Richer colors, deeper blacks. And overall, much clearer and crisp. And then OLED on top? Sounds great. Plus, adding glass to the back (again) will give the phone some needed weight, which is good because they keep getting lighter and more prone to slippage.
Also, for what it's worth, not sure if MR reported on this, but the rumor of Apple using OLED in the iPhone 7 Plus seems to be supported elsewhere:

At 60,000 sheets per month (e.g. probably >10x that when cut down into 5.8" sizes), both sites seem to suggest that OLED screens will find their way into the *next* iPhone, meaning the iPhone 7.
