One can argue that almost nothing is a new product then. Everything is build upon previous work. The iPod wasn't the first MP3 player but it was the best one out there and it changed the entirely industry. The same can be said about the iPhone, iPad, Apple Watch and pretty much all of Apple's products. They don't always come out with a feature first because they generally don't believe in releasing half baked products (Apple Maps withstanding).

For example the Motorola Atrix was the first smart phone with a finger print scanner, but if you actually owned one of these you'll know that it was awful. It wasn't until Apple put Touch ID on the iPhone that people actually were interested in using finger print scanners, and the rest of the industry followed suit and copied Apple, not Motorola even though Motorola was first.

Another example is app stores. Apple didn't invent app stores. But after the iPhone added an app store, it changed the entire industry because of how easy Apple made it for anyone to develop for iPhone.
