Interesting indeed, but my fear is that Apple comes up with their own currency that changes Bitcoin and people being dumb enough that they embrace that instead of Bitcoin. The only way this would help is if Apple accepts Bitcoin and nothing else.
There will be many imitators to Bitcoin (things that aren't even decentalized or limited in supply), and their faults which will become evident over time.
Apple Pay's "digital wallet" itself sounds like a borrowed term from Bitcoin's digital wallet, as one example. That doesn't make credit cards or dollars and better as far as their inherent nature goes. The US dollar loses value and becomes more worthless over time.
No matter how many tricks or innovations you create on top of the dollar, the fact cannot be avoided forever that the government is printing this fiat unlimitedly, and this will eventually collapse.
