I am going to argue Apple is an innovator. Invention isn't the only form of innovation.
in·no·vate/ˈinəˌvāt/
Verb: Make changes in something established, esp. by introducing new methods, ideas, or products.
Apple has for the last few years, over and over again shaped entire industries. They didn't create them, but they did commercialize them on the large scale. Mp3 players existing before the iPod, but the iPod absolutely shaped that market. "Smart" phones like WinCE based ones existed before the iPhone, but again -- they shaped a market. They did it again with the iPad -- a product class around since 2000, and pushed by Microsoft in 2002. In the past, they absolutely shaped the personal computer.
I am not currently purchasing new Apple products (Asus and Samsung are almost all my hardware), but I won't claim they aren't an innovator. When I look at the SIII, I am happy apple helped shape the market into something beautiful. I am also happy that Apple often pushes or drops new technology first...
That I said, I have absolute nightmares of a market where Apple wins and is able to really effectively drive out competitors. I only enjoy Apple for its side-effects not direct-effects. I hope that other companies (Microsoft, Samsung, Ubuntu) learn a bit from Apple, and grow some balls and try bold things.
