In the User Interfaces that you have used, be it in software, web-apps, games, or whatever, what stands out to you as the most important aspect of it?
I believe simplicity is the real winner here, but it seems more and more that polish is what gets rewarded? Innovation usually takes a backseat to both of these as it usually involves being too complicated and 'the masses' don't adapt to it. (Android?)
Case example: the iPhone. Which aspect of it's UI is more important to it do you think? The simplicity, or the polish, or maybe the innovations? Which one of these would be the killer to remove, and which would have to stay for it to have the success that it has had?
