If you have an iPhone 6 and you were thinking about upgrading to the new iPhone 6S, the answer is.... Yes. Here's why:
Top Reasons to upgrade to the new iPhone 6S
1) The case and screen are stronger and more durable. Even though the new model looks the same, Apple is using a stronger grade aluminum and glass for the case and screen respectively. These new materials are much more resilient to damage if you drop your phone. In fact the new materials are so rugged you might even consider using your phone desnudo.2) Applications runs faster and smoother. The new iPhone 6S has a faster processor and more RAM. This means compared to the previous generation (iPhone 6) your applications will open faster and won't lag. Overall when using your phone you will experience less stalling and stuttering. This is especially important since the latest operating system, iOS 9, seems to be slower than iOS 8.
3) Better fingerprint scanner. The fingerprint scanner (aka Touch ID) is noticeable faster and more reliable. Compared to the previous generation I notice that my iPhone unlocks much faster.
4) Upgrading to the latest model doesn't cost as much as you think. Because iPhones retain so much of their value you can sell your iPhone 6 on eBay or Swappa and use the proceeds to subsidize your new iPhone 6S. In fact a recent study shows that upgrading every year costs about the same as upgrading every 2 years (assuming you sell your phone private party).
5) The increase in weight and size are de minimus. When comparing both models side by side, you definitely won't notice the increase in size, and the increase in weight is negligible.
So overall I would recommend upgrading to the new iPhone 6S. If you take into account the benefits of the new features and you sell your old phone private party; I think it makes sense.
P.S. The pressure sensitive touch screen (aka 3D Touch) of the 6S has been receiving a lot of attention. My initial impression of 3D Touch is that it's a bit of a gimmick and it isn't really that useful. Perhaps my opinion will change over time but so far I've found it finicky to use and not very intuitive. When it does work I don't fee like it is doing anything exceptional. Perhaps my opinion will change over time and/or if developers come up with some novel uses for this feature. We shall see.
