Sorry, my bad, I meant examples of what Google has done that was a literal copy of what Apple has done in their OS.
I'm going to take a stab at this and say "virtually everything"?
Not saying I "know" for sure on this. But, before the iPhone. The best thing you could have that was close to it, was what Palm Treo? Or some Nokia Symbian OS? I'm guessing, as again I could be wrong. But, in any event. I don't remember Google having any kind of OS before the droid. There "droid" was supposed to be for BlackBerries next OS for their phone was it not?
Which wasn't really that close to what iOS was and currently is.
From what I remember (help me if I am wrong):
1) Internet sucked on every phone till iPhone
2) Mail was great on blackberry's
3) Contacts were fine on other phones too
4) Not really any apps for phones in the manner it is today since iPhone
5) Touch screens sucked (not as good sorry!) as iPhone's screen
6) Ecosystems (phones to PC/Mac sync, share, etc) sucked before iPhone
7) PDA's before iPhone. iPhones gave you a computer in your pocket.
8) All phones didn't have the "obvious factor" before iPhone.
My last point is my biggest. Due to the fact that each phone back then had something you wanted or needed or liked, or whatever. But they did not ALL have it. A Palm was good for "X", while a BlackBerry was good for "Y", etc. Each phone did not excel at everything. The iPhone (and iOS) pretty much changed that whole thing. You now had the ability to run applications on a small device that was designed to work on such a small device. NOT a dumbed down version of a full blown app. Not a add on like "web browsing" but, an application designed to show you the web on a small device. The "obvious" being that it worked right for what your using it for. No other phone really had that. Which exception to certain features "PDA" like, which worked fine for what it was needed for. Limits of hardware and of course software made each phone good at somethings not, great for everything. Hence why blackberries are going out, and so to with Nokia's old Symbian OS in favor of Windows Mobile. You had good parts, not a great product. iPhones changed that DRAMATICALLY.
Before the iPhone, you didn't have the choices you have now. Now, ever phone maker wants to be like the iPhone. And give you everything the iPhone can give you. Whether they are doing it better or worse is up to the buyer. But, so long as they don't "copy" a patented idea from Apple. They are free to do what they wish to provide the best experience they can with there product.
