Trying to switch back to a smaller screen is tough, even if you didn't want a big phone to begin with. Often I don't want to have a huge phone with me at all, but then I don't have a choice. The long term may be some sort of personal communicator (watch or otherwise.) Small screen, advanced input when necessary by voice. When people want to read things, write messages, watch video, play games, etc, then they can pick up their phablet -- which is effectively a phone sized tablet that fits in your pocket. The Apple Watch probably is the step towards this direction. However, because it needs the iPhone it misses the full use case, for the moment.
