I have a 6 and I'm thinking about returning it for the 6 Plus. I tried it in the store and I have no problems with the size. It fits well in my pocket and I have long fingers that are pretty capable of reaching all corners of the screen. My only qualm is that I often go to the gym and run with my iPhone in hand. I use it for listening to music but also like having it to track workout information, map my runs, etc. The iPhone 6 seems like it can still be used for this, but the 6 Plus might be unwieldy while running. Does anyone have experience with this yet? Is the 6 Plus too much of a beast to hold in your hand for a few miles? I'm weary about using armbands but I'm willing to hear suggestions.
