What do you think notification center is? Android had that a year (or two) before Apple. It was a blatant copy. And an improvement.
And thus my point. Apple's best bet is to copy Android and try to improve it.
Though I'm not sure I agree that Apple's is an improvement. Granted, I haven't used any Android older than 4.2.1, but the notifications seem pretty good to me. Better than iOS6.
Apple's integration of folders is much better than Android. It's implementation of Siri, is better. It's implementation of App switching is by far better.
That all seems open to interpretation. Folders on Android 4.2 works the same as on iOS6, so I'm not sure how one is better than the other. I've heard the Siri issue argued both ways, but I've never used that functionality for anything serious anyway, just reading text messages aloud when I'm driving.
I think all people are complaining about is that you can't have a bunch of tacky a$$ widgets on the home screen instead of the home screen being a much better designed app list view. Once you get behind the home screens on android, the whole thing is a mess. Their app list is a big unorganized scroll of apps. If you want them in folders you have to organize them on the unorganized home screens.
Eh, I kinda prefer it. I have a custom set of home screens with just what I want. Including tacky widgets that show me at a glance what the weather is going to be like for the next week and my calendar for the next few appointments. Useful and not an iOS feature. If I want to see all apps, I can get an iOS-style grid with one click, and it's all organized alphabetically (i.e. no having to use spotlight). I'll agree that the app list (where you manage apps, delete them, whatever, not the launcher) could use some love.
I think Apple's notifications across the board are better than what I've seen from Android as well. A flick of the power button and I know exactly what I've missed.
I can see what I've missed right on the status bar before I choose to swipe down and see the whole notification list. I don't have an AT&T logo wasting space up there, either.
I'm not sure what everyone is clamoring for I guess.
Call blocking. UI customization so that *I* can decide what tacky things I'd like on my homescreen. Lock screen customization. Swype. Even better, third party keyboards (Android's keyboard is better than Apple's, but wow, SwiftKey kicks both their asses clean out of the park).
Facebook videos on the home screen? Our friends funny pics from Twitter? I guess that's all cool and nifty, and I'd like that option too.
Eh, keep it

. That's something I'd *not* like on my home screen.
I'd also like some easily accessed setting panel to quickly turn on / off wifi, etc. But those are all seldom needed things. I like the whole package being more useable and functional.
Yep, got those on my N4, and I do like having them handy. Going through several levels of nicely-organized-but-painful-to-navigate hierarchy in the settings menu just to get to brightness is silly.
As for the package deal -- that's apparently something that was a problem for Android in the past. Along with responsiveness, something that kept me using iPhones for generation after generation, it seems like Google has made huge strides in improving the experience. Setting up my N4, I entered my Gmail credentials and it set up the phone, complete with auto-backup, just like iCloud does. The UI is consistent, responsive (no lag, seriously -- about time they figured that out given how powerful the hardware as been). Easy to use, and more personalization options than I've ever seen with iOS.
Apple had a good claim to constraining the features when the tradeoff was a stable, cohesive package. That argument doesn't apply anymore, so they're going to have to shake up iOS a bit and innovate.
