Tablets and smartphones existed before the iPhone. Online stores with micropayments for software existed before the iPhone. MP3 players existed before the iPod. Apple didn't invent any of those things.
In what moment I say Apple invent completely something? The old-excuse "before exist" but before (almost) nobody want it? Do you not remember how was that tablets & smartphone before the iPhone/iPad?
Not because everyone see what apple do, then try to copy it.
What was the thing that Apple do, and everything else copy it:
1- Switch to touch screen from keyboards & other inputs
2- The integrated solution (extreme case: MS)
3- The App store
4- Open the development to large pool of devs (before apple, was almost impossible that a person like me develop for phones)
4a - A decent cut of 30%. Back them, you lucky if get 10%
5- Provide decent toolset for devs (the MS toolset - Windows mobile- was the best back them. And was terrible)
6- Push for consumers, instead of business (ie: RIM)
7- Delivery tablet not like a desktop half-attempt at tablet, but with specialized software (7a: Specific api for touch enabled apps, 7b: Native development!)
8- Have a single OS across plataforms (extreme case: MS!)
9- ARM
10- Powerfull hardware (State of art? Windows Mobile like 64 RAM for disk+memory. When I know that the first iphone was 128 I can't believe it. Then the graphic card....)
11- Free, constant updates of the OS (barely matched)
And other things that I forgot. In the mean time, the ENTERY industry was put downside-up, MS lost it, but still have a last try, RIM/Nokia fall, Samsung rise from nothing, Google enter new batlefields and Apple rise to top.
YEP,
That was TOTALLY the innovation provided for others...
