Quick settings I agree would be great, but hardly game-changing. If they did add that, I believe it will be considered an incremental upgrade, just like adding copy and paste was. As for looks, well, if they made it look different but it did the same thing, personally, I don't see the point. And like, for instance, when they changed the look of iTunes by getting rid of the colors and making everything grey, they made it HARDER to use. So I guess I prefer they play it safe, and not change anything unless they have to.
As for giving people something people didn't know they need or want, as I believe I've said before, that kind of change just doesn't happen every year. Maybe the rumored Apple TV or iWatch would be that kind of a product, but I just don't see the iPhone getting any revolutionary changes. I mean, think about it, if the iPhone underwent a revolutionary change, it would no longer be an iPhone -- it would be another product. Like, when the MacBook got a significantly thinner and lighter body, it was no longer the MacBook, but it was the MacBook Air. A significantly smaller iPod became the iPod Nano. And talking about the Nano, that's a product Apple keeps on changing frequently, and not always for the better, lol.
