For me SE was hard in the eyes when browsing and even facebook the keyboard takes a lot of it tiny screen and i have perfect sight! One year and i was ready to move to the best size for me ever 4.7 screen no planing to go back
Hmm... To each our own.
I honestly don't browse much on my phone and don't use FB at all.
To me I simply want the smallest, lightest, most pocketable iPhone so I can hail a ride, message, make a call, take a photo, check a sports score, etc..
I really wish Apple would realize that some of us just need the most pocketable iPhone and that's all we want from our phone. I use my iPad (or Mac) for when I really want to dive in to content consumption or more task oriented things.
