Iphone 6s and Apple Watch

   About a month ago the new iPhone came out, the iPhone 6s.The new iPhone is a continueation of the iPhone 6. Then there is also the Apple watch that came out in late April. The iPhone 6s has new features like heavier due to better alminium to avoid bending, 3d touch on photos allowing users to pinch the screen to zoom, live photos to capture motion before and after snapping a photo, 3d touch which is used due to pressure sensitive screen to add short cuts, ect. The Apple watch has features like Apple pay, fitness/activity apps, different forms of showing the time, ect. The thing about all of these new gadgets is that are they really necessary? Maybe if you are a business worker or something then you could use it, but when I see kids in middle school or whatever age kid I think to myself, do they really even need that, so what if they can use the calculator every once in awhile but isn't this  just about competing with other kids or about who has the best things or the most recent (showing off). I don't know, what do you think?
