I wanted to give a quick update after having used the phone for a few days.
I mostly use my phone to text, make calls, browse the Web, listen to music, and watch shows. The transition to a smaller keyboard hasn't been a nuisance at all for me, but I do have smaller hands than some.
Transitioning from the 6+ I was mostly worried about having difficulty being able to read Web content and how the smaller screen size would affect my experience watching shows. So far I have been pleasantly surprised. I use Safari as my browser and find that enabling reader view really helps. I'd say it's available on 75% of the websites I visit. At first I didn't think I would be able to enjoy watching shows nearly as much as I did on the 6+, and while this is mostly true, I don't hate it at all as I typically only watch 30-60 minutes per day. I feel like the benefits of the smaller device far outweigh this and it is to expected that viewing shows is better on a bigger screen.
The most pleasant difference for me has actually been the form factor! I find that the phone is so much easier and enjoyable to hold due to the more squared off deign. As I mentioned in my previous post, the 6+ was my first iPhone so I had no experience with the 5s to compare it to.
The SE feels snappier and the battery lasts me just as long as my 6+ ever did. The difference between the second and first generation Touch ID is negligible for me. So other than the screen size, I feel like I gained more than I lost with this trade.
Hope this helps anyone else considering making the trade from a 6+!
Glad you are happy with your choice!
Just a thing to note: if you did come from a 6+ and not a 6s+ then you should know that TouchID is first generation on both the SE and 6+!
