There is a difference between not being first and not being innovative....
Before the iPod, all MP3 players were either big and clunky, and used fragile laptop hard drives, had slow interfaces to computers (parallel ports, USB1) or were low capacity.
Before iTunes, most of the music stores had weird and complex music licensing rights - even Bill Gates was amazed at the lax licensing that Apple was able to negotiate.
Before the iPhone -- the smart phone market was made up of glorified pagers (BlackBerrys), shrunk windows PCs (Windows Mobile) and Symbian.
Before the iPhone most customers were at the mercy of the carriers who decided when you could update your phone and no manufacturer stood behind their phones for up to four years after you bought it ---my bad things still haven't changed for Android users.
Before the iPad you had over a decade of clunky MS tablet failures.
