So I've been surfing on and off using my wife's iPhone 6s and my 5S side by side. Because of my old eyes, I've been having more and more problems focusing on the small fonts on my iPhone. Presbyopia is a bitch. My problems with near focusing are a lot worse now than they were just 2 years ago.
The additional problem with my 5S is that there is no true zoom mode. Although in standard mode, the font size of the 6s and the 5S is the same, on the 6s there is a zoom mode, which increases the font size for everything, which makes it easier to read. The problem there though is once you increase the font size, you effectively lose the screen real estate advantage over the 5S in real terms. It's bigger but doesn't have significantly more content width-wise say when you're surfing. This has also become a problem, since many websites are now targeting 4.7" phones but with standard font sizes.
The 6s fits OK in some of my pockets, but now I'm wondering if I just take a chance and plunge into the 5.5" category. Personally I think the size of the 5.5" phones is ridiculous. They don't fit well in many pockets, and they are absolutely impossible for me one-hand, but I already have enough problems one-handing the 4.7" 6s. (I have small hands.) That's why I've clung to the 4.0" sized phones for such a long time.
One thing that makes me consider the humungous 5.5" is the improved camera. If the 5.5" is the only one with a dual-camera as rumoured (see above) and is the only one with optical image stabilization for both video and still photos, I may give one a shot. The bigger size would also make it more pleasant for viewing photos and videos. I'd probably still carry my iPad around to some places though. 10" is still much nicer for videos compared to 5.5".
Too bad no OLED for the 2016 though. OLED has its problems too, but I'm sure if Apple used OLED, it'd be top tier OLED with great colour balance. I'd almost be tempted to wait for 2017 to get OLED but there's no guarantee it will get OLED until 2018, if at all:
