I was just thinking.. why would Apple release two different screen size iPhones. They have never done this before. Then I started to think, would it be possible Apple is testing the larger screen size market? By making two phones, they get an idea what there audience wants and how to accommodate it next year. They also have almost no room to fail. If people don't buy the 6+ as fast as the 6, they found their sweet spot. Judging by the overwhelming response of the 6+, I think Apple didn't expect such a demand for such a large jump in size and are going to plan much more accordingly next year. While maybe possibly bumping the 4.7" iPhone 6 to a 5" next year? Just my shower thoughts about this.
