Tell me: How many post Apple I/II inventions of Woz are you familiar with? He certainly hasn't stopped inventing. He just doesn't worry about selling inventions any longer...
The iterative improvement that Apple uses to design and perfect products is somewhat darwinian but it lacks the random mutation and recombinative aspects that define evolution. I'd have to say (since the water has already been clouded by this new little corollary of Godwin's law) that it more nearly approximates intelligent design.
Incidentally (to the OP), you always make multiple designs before you pick one. That's not loss of artistic process. I've got three drafts of a single chapter of the book I'm working on now. I've got something like 5 different possible melodies to fit a song I've been Garagebanding. That doesn't take away from the power of the individual when it comes to designing a product. (Considering how in-depth people have looked at Jony Ive's design process and inspiration, I find it sad that people still think Apple products are made through a generic idea-forming process, that the people barely matter in the creation process.
(Also, this author is not a particularly good one, and the fact that she's citing Tom Waits is not a good sign. Waits is a legendary practical jokester and story spinster, and all reports of his songwriting I've read say that he undergoes a very strict process when constructing his songs.)
