I waited till the end of the day to post on this 'story' from the journal. It is a useless story and has no new findings whatsoever. It is so rhetoric that I dozed off a dozen times trying to finish reading it. Apple came up with the idea of a touchscreen device much before iPhone was introduced in 2007. It is also a well known fact that the iPhone was an afterthought and Apple always wanted to come up with an iPad first. So it is also a well known fact that Apple is testing devices with multiple screen sizes.
Again the news that Apple is willing to venture into different screen sizes for its touch screen devices was evident more than clearly when the iPad mini was released. And from the iPod line up we know that Apple is not reluctant to diversify a product line up. But the key is what Apple has reiterated many times in the past, a bigger screen iPhone/iDevice will be introduced when Apple feels that the technology is ready and when they feel that the market is up for it.
Also as I mentioned previously in my post on a bigger screen iPhone and the next big advancements in iPhone hardware we can expect, while I would not mind a bigger screen than the iPhone 5’s 4” screen, I would not want the one hand use of the iPhone to be compromised. And I think most of the sane people prefer to use a smartphone as a phone with one hand and not as a tablet with two hands! Why is this so difficult to understand? I am not saying there is not a market for a bigger screen iPhone, certainly 4.3" to 4.7", may be, but Apple is not going to start offering bigger screen iPhones just to increase its market share and to 'compete' with Samsung for higher world wide shipments. The key difference between the 'throw a bowl of spaghetti at the wall and see what sticks' - Samsung and Apple is that Apple cares only about the product it releases for the customers and the its quality.
No... Samsung is able to bring products into the market more quickly because they do not care about the quality of the products they put out and they blatantly copy other successful companies for almost every one of their products. Hence they have no need for real R&D or any other 'bring to market time', that is normal for any other moral technology company!
In short no useful or new information from this article and so has been the trend with the journal for a while now, sadly!
