I don't think the 5.5" iPhone will launch at the same time as the 4.7" iPhone either.....
And I think Apple will quickly do away with the difference the next generation. I just think if we are getting some sapphire display, it'll be split by line rather by storage space.
You could say the same thing about those who want a 32 GB phone but also want sapphire. Do they just have to "suck it up" and pay more for the 64 GB just so they can get sapphire?
Honestly, it would make the most sense if all this sapphire business was purely related to the iWatch and NONE of the iPhone models got sapphie displays this go around. Next year, they all would (well, all the new models would).
Hey I think if Apple's going to use sapphire it should be on all flagship models. But if there is a supply issue I'd rather they limit it based on price than screen size. And Apple just happens to use storage size as their price differentiator. IMO screen size is more of a compromise than storage. If I really wanted sapphire and was willing to pay more for it I'd take the additional storage.
