> - Dark theme. Customization = good. Sends a good message.
I'm not sure if the customization option would come anytime soon, but a dark theme would very likely come out in 2017 when Apple releases an iPhone with an OLED display. It most likely wouldn't come if the lineup is all LCD (as it has been so far). This is all about battery life, which Apple obsesses about a lot. Assuming there's just text on the screen, with LCD, black text on white background would be better for battery life, whereas on an OLED screen, having white text on a black background would be better for battery life.
Edit: While Apple has shipped (LCD) iPhone models with new versions of iOS and sometimes darker wallpapers, my point above is more about many of the Apple apps, including Settings, Mail, Reminder, and so on.
I love it that they are obsessed with battery life. It seems very few OEMs remember what a mobile device is these days. I like Apple for it very much.
That being said, I would buy the OLED iPhone in a heartbeat but only if it has bezels and has no curved screen. These fads are making normal human usage of the phones a huge annoyance and really need to die.
I'm very sad that I am seeing exactly the opposite: many people FINALLY got their brains warmed up and figured "Hey! Samsung did it, look how well their S7 Edge sold! Let's do the same!"... that's awful, sigh. They absolutely don't get it.
