Apple is very very good at looking at new technology coming down the pipeline and figuring out how to turn it into something that consumers want; the iPhone was probably the biggest example of this in their history, they seized on the potential of capacitive-screen smartphones just a bit before anybody else did, but they do it in all sorts of product lines; the new MacBook Air is going to convince every other laptop manufacturer to start designing machines around on-board flash storage instead of around standard-hard-drive-bays-into-which-one-might-insert-an-SSD, just like the iPod Nano hastened the move towards flash-based MP3 players. They also execute amazingly well, the occasional Antennagate notwithstanding - only now at the end of 2010 are we starting to see other touchscreen keyboards rival what the iPhone had in 2008.
(I won't even talk about my frustrations using an HTC Desire as my primary smartphone for the last 2 months after 2+ years of using an iPhone, since that's just going to turn into a 3-page Android-versus-iPhone pissing match of the sort we've already had a couple of in this thread - suffice it to say that my previously not-very-well-informed anti-Android stance is now extremely well-informed and no less strongly felt, though waiting weeks and weeks to get Pleco OCR out due to the iTunes review process is making me hope Google pulls a rabbit out of their hats for 3.0)
Anyway, I don't know whether to call what Apple does "innovative" or not, but it's a form of "innovation" that's close to my heart since it feels very similar to what's made Pleco successful - taking a bunch of cool new inventions from elsewhere (handwriting input, 200,000-entry dictionaries, high-speed Chinese OCR), combining them into a polished, generally-well-executed product and charging whatever we have to to make that come together.
