Apple has never invented anything truly innovative.
All they do (and all they have ever done) was reinvent the wheel. They do, however, consistently reinvent the wheel better than anyone else.
Case in point: In literally the year 2000, I owned an HP Jornada 548 pocket pc, complete with a wireless modem that worked on cell phone networks. It ran Windows CE, and I was able to surf the web, use AOL instant messenger, ICQ, do voice recordings (even transcription), handwriting recognition, play games, and yes, even make phone calls. But it was clunky, and it wasn't something that I would even dream of recommending to my grandmother (because the UI was terrible and slow, and it required a lot of fiddling with things to get it dialed in the way I liked it).
Contrast that with the iPhone (which was released a full 7 years later). Was it the first smart phone? Obviously not. But it was the first smart phone that I could honestly recommend to my grandmother.
