Apple to launch iPhone mini

Apple is rumored to launch a compact/ mini version of it's iPhone. the device is said to follow the design philosophy of iPhone 5s. It will come up with the 4 inch display, new A9 chip, 1 GB of RAM,  8 mega pixels iSight camera, updated FP sensor and force touch.

The apps today are designed to take full advantage of bigger screens, and at 4.7 inches the iPhone 6s is still not feel that big. 4.7 is the new sweet spot now a days, so it is not quite clear who are the targeted customers for this phone.
