For folks that are using an iPhone 6 Plus and who came from a 5/5s - How long did it take for you to adjust to the large size of the 6 Plus? Once you got used to it, did it start feeling natural? Do you ever find yourself in any situation where you feel like you would have preferred a smaller device? Once you go with the 6 Plus, is it hard to go back to something with a smaller screen size? I am thinking of upgrading from the 5 to the 6s Plus this Fall and would like to know your thoughts.
