When people say Innovative, we think of something that when we see it, we go Wow this is so cool I would never think of of that myself, and usually throws the rest of the industry in catch up mode.
Now the iPhone (not the iPad) was an innovative idea. Phones before the iPhone had external keyboards, at the expense of of screen size, or thickness. The idea of very few real buttons at the time was very foreign to us. And using gestures seemed almost impossible, as many early gesture systems had a lot of complicated gestures to get tasks done.
The iPhone wasn't innovative based on its features, there were other companies that had phones with more features or better hardware. But the innovation was able to successfully make a phone, that the advance feature were accessible and to the end users. The idea of say browsing the web on your phone, or have it as your main method to check for email seemed silly before, today it is quite common.
What happened after the iPhone kicked off, it threw the Industry in catch up mode. It took years for good Android phones to get into the market to start competing, and these new phones all are based on the iPhone.
Now the iPad isn't that innovative, it was easy to realize you take your iPhone and just give it a bigger screen, and fit better processing.
Other innovative products.
ID software 3D shooter. Wolfinstine 3d and Doom. They had some wire-frame attempts, and a few polygon based games. But games before that for the most part where 2d sprite based (Side Platform like Mario, or top down like Zelda), specificity for fast paced action games.
Nintendo Entertainment System. Unlike the Atari and other predecessors it didn't give any allusion that it was a person computer, just a straight game console. Priced more affordable than the others, and focusing on games.
Innovation is very rare. Most of the time it is copying someone else idea and tweaking it so there are different set of trade offs. Now their tweaks may change the market, but not as much as a innovative product.
How you choose to license your product, isn't really that big of a deal. Open Source, sure people can tinker with it coming with some new ideas. Commercial Software will have paid employees trying to come up with something new.
