Then, just like there’s an 11- and 13-inch MacBook Air, and a 13- and 15-inch MacBook Pro, there’s a 4- and 5-inch iPhone, and a 7.9 and 9.7-inch iPad.
Almost 9 out of 10 AT&T customers bought 4-inch or smaller iPhones last quarterrather than all big screen Android and Windows Phones combined, and roughly 6 out of 10 Verizon customers did the same. So aside from geeks who keep posting about how they really want it, and shoppers for whom bigger as a feature is always better, Apple might not feel any pressing, mainstream need to add another screen size to the iPhone product line. Yet.
But if and when they do, stretching the screen offers less complexity, and less impact on both iOS and developers. That’s how you expand a product without expanding panel production or developer support headaches. It’s an Apple-like solution.
Apple hasn’t released a big phone yet because they haven’t had to in order to be successful. If it does release one, the history of the MacBook line and the release of the iPad Mini indicate that a 5-inch iPhone would have interface elements of the same size as those on the 9.7-inch iPad and the same pixel density screen as the iPad 3/4.
I find this theory likely because it a) makes logistical sense, which makes it seem like something right up Tim Cook’s alley, and b) it lets Apple cover even more price points. My addition to the theory: Apple also release a 5-inch iPod touch Plus at $299, and makes the 4-inch iPod touch the $199 model. That would make the $200 model a steal of a bargain and the $299 model an even lower-priced tablet option than the iPad Mini. This also has the benefit of an easy upsell: Apple won’t include a cellular radio in an iPod touch. If you want LITE, you either need to buy an iPhone (and if you want the big screen too, an iPhone Plus) or an iPad.
