Recently, the new products of Apple, Iphone6 and Iphone6Plus have gone public. One of the most distinguish features of these extremely popular Phones is that they have very large screen. The screen size of Iphone 6Plus is 5.5” which is very close to the screen size of an Ipad mini. So why does Apple make such big Phones that seems to contradict with its other product making Ipad in an awkward situation. In my own opinion, it is because Ipad has a lot of close substitutes and it does not have a clear value proposition. Nowadays, it is the fact that Ipad sales are gradually decreasing, many companies have found that the electronic pad is profitable and started to produce. For example, there are Sony Pads, Lenovo Tabs and even more pads that use Android system. So it is very hard to win this turbulent competition. Also Ipad is designed for gaming and reading and doing office works. So compared to a IPhone that has similar big and high resolution screen, Iphone is more easy to carry. And compared to desktop, Ipad is less convenient and powerful. Do we really need an Ipad if we can read and play games on a Iphone 6Plus?
