I don't think that going forward they will produce any more small phones. They may keep the 5s as their small phone, but if the numbers trend higher towards the larger phones, then say bye-bye to the small phone.
Apple overestimated 5c demand. People here are underestimating the demand of large size 6 phones. The world wants larger phones. The phablet is the de facto standard in Samsung's home country of South Korea. Things don't have to go that far, but people want more screen real estate. With the technology, that can be done without making the overall device significantly larger. Remember that there are 7.2 billion people on this planet, and only 322 million of them are in America (4.45%). The adoption of cell phone technology is spreading at a rapid rate, so what the US wants may no longer be decidedly relevant when it comes to phone size and design
(most of the macrumors users are from the US).
I do agree with the other posts that the home button needs to be rethought. Move it to the back, shrink it down, something. Maybe sapphire will allow them to eliminate it all together and move its' functions to the screen.
There should also be no reason that a new 64 bit iPhone 6 shouldn't come with at least 2GB of ram and the option for 128GB of flash storage. And if the capacities are there, the the apps will come to take advantage of them. I want a camera that will blow any of the Lumia cameras away. I know it's not all about megapixels, don't get me wrong. But Apple has rested on its' laurels for too long, thinking they can just put out a device telling the consumers this is what they want and expect it to be super successful. The competition is running circles around them with the advances they have made and are putting out in the market. It may dilute their brand and clutter the market, but at least there are options out there for people who want different things. We've come a long way from Henry Ford and his famous Model T quote.
