The only real feature of note was Apple Pay, which might finally make NFC payments take off in the US. It's been a technology that should have hit it big a couple of years ago, but has never seen much consumer buy-in for some reason.
Because no one unified around it. You have credit cards and phones and all that, and the phones were all fragmented into using Google Wallet or other custom thing so it was impossible to actually use.
Effectively, Google thought "If you build it, they will come" and everyone basically gave a collective "meh" and promptly did their own thing.
What Apple did was try to be a de-facto standard. Apple made deals with Visa, MasterCard and American Express (which probably covers the vast majority of credit card charges out there). Apple made deals with big retailers people used. So in the end, Apple has, upon launch, the support of the vast majority of credit card payment companies, and big companies that most people shop at.
Plus, Apple has money on their side - the people who buy Apple products tend to be ones who have money, and are the kind of people who do spend it. Android users tend to be more tight-asses (given the vast majority of them are free phones that their carrier gave away), so are in generaly seen as a "lesser valued" market.
So you have companies agreeing to Apple because they know Apple customers generally have money. As a side effect, it means the technology being promoted gets widely distributed so everyone else benefits as well.
