Why Apple not Launch Bigger Size iPhone ?

Although Tim Cook in last month's discussion of the 11th Conference on AllThingsD industry has expressed interest in large-screen phone completely, but obviously Apple is planning to launch with a larger screen iPhone, and that the plan should not be Apple's recent whim before deciding.
Foreign technology media Techno Buffalo believes that if from now on the development trend of smart phones, Apple is likely to be introduced in the future 4.7 inches of the iPhone, but 5.7 inches giant screen iPhone probably just anyone's guess.
First of all, Apple has a unique marketing strategy. While Samsung and LG have now launched a giant screen phone, but also in the market with great success, but this is not Apple's style, Apple will not imitate its competitors and launched a similar product. From iPad to iPad mini evolutionary process can be found, unless there is a huge market demand and a sufficient degree of product differentiation, or Apple would not blindly enter the market. Precisely in order to attract public and iPad users who prefer a cheaper option, Apple just introduced the iPad mini.
For Apple, the smartphone market situation is different with the tablet PC market. Giant screen phone prices even higher than the iPhone. If Apple introduced the iPhone giant screen, then Apple will enter a previously made by Samsung and LG dominate the market, so want to get ahead is not easy. And even if the giant screen of the iPhone and Apple products are now large enough degree of differentiation, but the premise with iPad mini, iPhone launch necessity giant screen is not large.


Why Apple will not launch large-size iPhone?
Secondly, the Apple iPhone has been a very valued one-handed ease of use, Apple iOS want users to be able to help with one hand to complete all operations. From this perspective, the giant screen Apple iPhone also contrary to the Principle. This is why Samsung and HTC Android users want to be able to emulate Apple's approach, the introduction of a smaller screen but more powerful phone. And if the launch of the iPhone 5.7 inches, then due to a combination of the big screen and the advantages of mobile communications features, so giant screen iPhone is likely to be a threat to iPad mini or even a full-size iPad sales. So the iPad series was a great success today, why Apple iPhone giant screen to launch it?
Why Apple will not launch large-size iPhone?
Once again, Apple does not bring new products to worry about market performance. With the analysis of the market, Apple has been convinced that their products will meet the needs of most consumers, which is why Apple will not launch cheaper products, but by reducing the price of the old product to attract consumers to join the limited funds Apple's ecosystem. Although there are rumors that Apple will introduce a low-cost version of the iPhone to expand the market, but do not forget the cheap version of iPhone for China and other developing market launch. In recent years in developing markets, due to the rise of local manufacturers such as Nokia and developing markets have experienced manufacturer developed a strong, Apple faces increasing pressure, so the introduction of low-cost version of the iPhone is also reasonable.
In summary, although there are various advantages of large-size iPhone, but Apple probably will not release the final Reuters in 5.7 inches iPhone, at least in the short term is impossible.
