I have been trying the new iPhone 6S recently, and while it is an improvement on the 6, I cannot say that it is a dramatic improvement.  Every phone has improvements every year and I think the improvements that make this a must have phone would depend on what you do with the phone.  If you are recording a lot of videos, for example, of your child and you want it to be relevant in years to come, then you need the iPhone 6S, because it now films in 4K resolution which is obviously four times better than the quality of the previous version.  I like the live photo feature also which means that when you go through your pictures and you press on it the picture starts moving, essentially showing you a video of what happened about 1½ seconds before you took the photo until about 1½ seconds after you took the photo and so it essentially makes your photos, while they are being seen on an iOS device live complete with sound!

Apart from that, the 6S uses a superior chip, the A9, and the camera has been upgraded from 8Mp to 14MP which, for a phone, is really breathtaking and it is putting into one’s hands these days the kind of cameras that professionals were buying for R30 000,00 only 3 or 4 years ago.  So, the videos are going to be better, the pictures are going to be better and everything is going to run a bit faster, but it is not truly dramatic.  The big feature that everyone has made a big song and dance about, which is the touch or 3D feature of it, is not that dramatic to me.  If, for example, you are going through your e-mails and you press a little bit harder on one of the e-mails it pops up while you are still holding it so that you can still read it and the phone has learnt to detect, depending on how hard you push the screen, to open it up for you or to just open it up partially, etc.  I am sure more applications will come along that take advantage of this in the future, but right now I cannot say that that impresses me. To me the main purpose for getting the phone was firstly a wife who does not mind using the previous model so when I upgraded she gets my old one and secondly, I really liked the live photo and in particular the 4K video.  If somebody for example asks  me now  what video camera to buy to make videos of their children, I would say it really does not matter – as long as it is 4K, but you cannot do the 1080HD anymore when something four times better is available and will obviously stand the test of time better than the 1080.
