On paper, the 2 main selling point is 3D Touch and 4K video but there are other improvements that comes with the phone and from my experience:

1. Battery life - far more superior than 6+, no joke. The phone also runs cooler despite continuous usage, clearly an improvement over the A8 chip.

2. Faster CPU & more RAM - The 6+ was a bit laggy/sluggish but the new 6S+ is blazing fast, smooth and crisp. The extra RAM also helps when you multi task, open multiple windows in Safari, etc. Games and apps load insanely fast.

3. Faster LTE - Same network, same spot but with the 6S+, the speed is much faster.

4. Camera - Improvements to it and front camera now captures much better quality selfies.

It's subjective on how everyone justifies whether it is a good upgrade or not and besides, it's up to us on how we use the phone. When we buy something, it doesn't mean we need to use ALL the features. We buy something because we love and want it. People that dictates how others uses their stuffs are just pathetic

For the same reason, a 40 year old woman can buy a Mini Cooper S but is it a concern if she uses all the features, if she speeds, if she takes sharp corners? She buys the damn car because she wants/loves it

Hence, just decide if it's a good buy for yourself and most importantly, you need to enjoy it. Personally, I feel that it's a good upgrade. Just my 2 cents.

I have an iPhone 6S Plus 64GB Gold from Maxis this Friday. Anyone interested can PM me thank you

I just got mine from Maxis and would like to sell it below retail price Click on my signature or PM me if interested. iPhone 6S Plus 64GB Gold

You can't carry this "good gaming rig" inside your pocket like how we can do it with an iPhone I suppose? Better hardware doesn't mean anything if the OS and user experience is not optimized. The point I want to make is, people spends on the iPhone because they love it.

He's checking iPhone 7S I went to App Store and all colors/models are 1-3 business days as well.

Anyone with iPhone 6S+ feeling some sluggishness/lag after upgrading to iOS 9.1? Basically some of the animation is a bit laggy when it zooms in/out.

Mine has been many days, still the same. I notice this big difference especially when you are in the multi tasking tab. Once you select the app and zoom in, the animation is sluggish. Previously very smooth and fast

Sell it off and buy again until you get a TSMC?
Mine is also Samsung (btw).

Try cleaning up the Home button. Obviously if it's dirty, it affects the ability to read finger prints.

Never had issues with the sensor 6 or 6S. My family members are all on iPhones and no problems with it as well.

From another angle, the color becomes different again. This article seems to be somewhat true:

https://www.quora.com/What-percent-of-the-p...-is-color-blind

Colour (color) blindness (colour vision deficiency, or CVD) affects approximately 1 in 12 men (8%) and 1 in 200 women in the world.This means that there are approximately 2.7 million colour blind people (about 4.5% of the entire population), most of whom are male

Just joking Under bright lighting it does make the pink "softer", not the angle.

For those that has 6S Plus and doesn't like that frame drop issue (like myself), just update to iOS 9.2 Beta 1. It fixes the problem and all you need is register for the beta program (google and follow the instructions).

Since it's Beta 1, new changes are minimal from iOS 9.1

I think to answer the color question, all you need to do is ask him.
As for the size, 16GB is possible because they don't use a lot of apps and all they store is mainly photos.
