Apple working on new 4-inch iPhone, 12.9-inch iPad for 2015?
Although Apple increased the iPhone 6's screen size because that's what users wanted, it probably won't go as far as removing the 4-inch option from its lineup. Not only it seems like a natural fit for a cheaper device that doesn't have to push high-resolution content to a big screen that facilitates it, but it will also please iPhone loyalists who are accustomed to the smaller form factor to the point of rejecting bigger displays altogether. Sounds like hitting two birds with one stone!
Additionally, Arcuri suggests Apple has a 12.9-inch iPad in the works for Spring 2015. He believes a larger tablet will be a fresh new look at the product category, and estimates 15 to 20 million initial shipments of it.
