In my last related post, I had a iPhone 6+. Like a lemming, I upgraded to the 6S+. The touted difference was the ability to push harder or softer on the screen to achieve a myriad of different actions based on how hard you pushed; not features I really use frankly, and I didn't really notice much of a difference other than the thing now being a lot heavier.
Like a faithful lemming, I've upgraded to the 7+. It does have a bunch of differences (color, faster, etc), but the two key ones for me (and the reasons its worth getting frankly) are;
- Its waterproof - I'm not a surfer, but knowing that I can get the thing wet and not stress / lose data is a big deal
- The second camera being used to create portraits with good bokeh and/or being able to zoom in quite closely is very useful on a daily basis
If you're debating getting one, don't debate too long. Apple has clearly reached the point where massive steps in innovation are not present. But, the incremental ones are not bad if you skip generations (i.e. buy, skip the next one, buy, skip the next one, buy)
