I'm still not convinced. I've said for years that I'm not thrilled with this whole size creep of screens - and people said that I'd change my tune at some point and that hasn't happened (yet). I have an iPhone 6 and I've never loved the screen size - or more accurately, the size of the whole phone. I take my phone with me when I go running and it doesn't fit in my running shorts so now I wear a waist pack to hold it. Plus when I roll out and run 16 miles (like I'm planning on tomorrow), I don't want to haul any more weight than I need.
You could say "dude, leave the phone at home" but one in the last year I needed the phone to call emergency services for another person (woman crashed her bike, found her comatose in a pool of blood) and plus I'm running for >3 hours and want to be available if my wife calls for something. Plus joggers are always the ones that find the dead bodies and so when my day comes, I want to be ready for it.
I know that I'm not in a common category with this whole running thing, but I know that I'm not alone in my general love for smaller phones... although I am probably in the minority on this forum.

To be honest I really wish I had never sold my iPhone 5... I like the camera on the iPhone 6 and I needed a new phone because I switched carriers to T-Mobile... but I should have gotten another 5.
