The only thing that makes me believe that I wouldn't need to upgrade to the new iPhone 6 or whatever its going to be called is the fact that I use my iPhone sparingly now. I generally use my iPad for multimedia purposes and just my iPhone when I'm away from home or on the go. An upgrade really wouldn't do much for me. I may just upgrade because I have an upgrade available, but it wouldn't matter much, because I would still use my iPad for most of the fun things. Also, is the reason why I'm not hard pressed for a bigger screen, because I really don't need one. Currently, I have the iPhone 5S, iPad Mini Retina, and iPad Air. I believe that I am thoroughly covered.
