Whilst a bit disappointing, I have to say that my experience with ING has been fantastic. The app is really good (and is Universal... it's one of the only apps that takes advantage of TouchID on phone and pad if you have it). I've had to call them a few times and they were just wonderful on the phone (and they were local).
They aren't my main bank, but I bet they'll be on Apple Pay before CBA (who are my main bank). I'll continue to use them even without the 2%, because I like the way they do business.
They don't have a credit card, but it sounds like they will have one soon and I would happily switch to them, particularly if it's on Apple Pay.
