I'm not arguing for or against it - I'm quite happy with my 5S but also think it makes sense for Apple to offer multiple screen sizes like they do with iPads and Macs. I'm just interested to see how Apple announces this bigger phone to the world. Will there be something about this bigger phone that is so much better than the competition that it won't look like Apple is playing catch-up? I hope so. I'd love it if 2014 was 2007 all over again.
Actually, just back in comment #197 of this comment thread I did exactly that (explained why, in 2012 or 2013, apple might not have felt ready to build a larger screen iPhone, but in 2014, with their sapphire deal, they are now ready. Here's that post again so you won't have to scroll back to it:
#197: Actually, a spreadsheet and some basic math skills can yield remarkable insights. For example, the current iPhone is 2.31" wide, but the display is 1.94" wide. If Apple were to extend the screen to the edges, using software numbing to ignore touch input at the edges, thus creating a virtual bezel (easily accomplished) and maintaining the display's current 16:9 aspect ratio, the screen could grow to 4.3" diagonal measurement without increasing the width of the handset. The top bezel could be shrunk to accommodate the greater height of this 4.3" display (perhaps this is why Apple moved the headset jack to the bottom back with the iPhone 5 in anticipation of decreasing the top bezel). With these changes you could have a 4.3" display in a handset the exact same dimensions as the iPhone 5 series handsets.
What's more, going side edge to side edge with a 4.85" 16:9 display would require Apple to widen the handset less than 1/5th of an inch. This iPhone would be slightly taller too, but at only about 1/5th inch wider it would still easily qualify for one handed use. So perhaps there is a reason Apple has waited; they didn't want to compromise on an edge to edge display being covered by gorilla glass, which falls at about a 6.5 on the MOHs hardness scale, versus 9 on that same scale for sapphire (diamond, by comparison, is a 10, the hardest substance known).
