Flat UI, is it enough?

I was wondering what iOS would look like if it were 'flat' as rumored and I stumbled upon this little concept. It certainly looks nice, much cleaner than the current design but is this really enough?

If iOS was 'flat' would you run out and buy an iPhone? After seeing this, I'm not so sure I would. Sure it looks better, but if nothing changes other than the UI, I don't think it would be enough for me to run out and buy another iPhone. I currently use a Nexus 4 and I love stock Android; it made me realize how much I was missing out on while I was using iOS.

Unless Apple makes some fundamental changes within iOS I'm not sure they can get me back regardless of how great the hardware is or how great the apps are. Android gives developers the ability to truly integrate deep into the system to provide users with a great user experience -- Apple's sandbox just isn't deep enough.

At first, Apple was right, they did provide a vastly superior user experience when you compared mobile operating systems out of the box, but most of the innovation is now coming from third party developers and Apple has them all trapped within the garden along with the users. I don't want to live from app to app, I want the experience to feel natural. The apps work great, most of them work flawlessly, but there's no synergy between the apps and the operating system itself, I want apps to feel native as if they were baked into the OS. Android has the ability to provide developers with this type of integration but unfortunately most of the high quality apps arrive on iOS first or are exclusive to Apple's platform.

This is just my personal opinion and I'm sure some of you have your own idea of what Apple would have to do to get you back or make you switch from Android. For me, they need to open up a bit and at the very least allow me to change default apps. A change in UI is nice but I would much rather be able to switch my map client to something that actually works.

*I use both Android and iOS everyday. I use a Nexus 4 as my personal phone, I still have an iPhone 4S as my work phone but mostly only use it to make calls. I also have a Nexus 7 and iPad (4th gen).

Is a flat UI enough for you? What would Apple need to do within iOS to put the next iPhone in your pocket?
