I didn't know I could put all sorts of re-sizable widgets on my old desktops or use things like gesture shortcuts that eliminate the need to navigate to apps or even have to launch them in the first place...
By that logic nothing is ever really innovative.
Not nothing, but you are getting close to the point. If you want to get right down to it, then very little can be properly labelled as 'innovative'. Until the introduction of the CVT, there was little innovation in automotive hardware. What's innovative in your kitchen right now? I mean in the last... 10-15 years people suddenly noticed this thing called ergonomics, but past that, a measuring cup is still a measuring cup.
The iPhone came out in 2007, and you can argue prior art all you like, but the iPhone came out in '07, and changed the landscape. They provided a new and creative way of interacting with small devices, namely through multitouch, and made them more powerful than they had been in the past. Since then... what have we gotten?
You had mentioned before about how being on the bleeding edge of software development Android.. something something... I would argue that that is not innovation, but more simply a rapid release schedule, and refinement as well. As Bearxor showed in his images, the interface of straight Android hasn't really changed a whole lot either, it has just been refined, iterated, and improved.
Re-sizable widgets: What do you think the windowing metaphor is?
Gesture shortcuts: How about mouse gestures from firefox?
You can take a stock, bought from the store Android phone, go into Google Play, and download widgets, apps or launchers that will completely change your homescreen layout to suit your needs. Some add minor touches like additional gesture support, and some (like TSF Shell) are major overhauls:

But the point being, stock iOS is stock iOS. Doesn't matter if you have an iPhone 3GS or an iPhone 5, the software experience will be very similar because Apple's slow iterative updates cater to the lowest common denominator. I guess that's great for people who want legacy device support, but phones from 2012 are completely different beasts than phones from 2009, and I'd rather have my mobile operating system take full advantage of my 2012 hardware.
And that's great, no one is saying that it is a bad thing. What it seems that Bearxor and I are saying is that it is NOT innovation. And I am not sure why you brought it up.
