that's the payment experience, sure, but there's all those moments before and after your payment. say, adding a card, managing which cards you want to use at which locations, etc. there was plenty of footage in the live stream this morning, or stills here: http://www.apple.com/apple-pay/
but the bigger point: you're quibbling over the first of three points i made in an aside (the other two being that google wallet has way more features, and that google wallet is now not blocked from being on Verizon et al). The larger point is that the article saying that this is the first OS to have a payments solution is... very strange.
Well, there's the second half of that sentence which qualifies it with "broad, inclusive". I'm not saying I agree, although it could be that Apple believes Google Wallet was not broad, inclusive, or both.
