Apple has always been cutting-edge about GUIs, ease-of-use and look of the product.
Apple is rarely cutting-edge about anything else. Apple generally waits to see something become successful before re-implementing it, and making it easier for the masses to use.
There are exceptions, like FireWire, Thunderbolt or Retina screens, but generally Apple finds something that should work and has a market, but isn't working in it's current form - like music players and creates the iPod, phones and creates the iPhone, or netbooks and creates the iPad.
And Apple generally doesn't include the latest and greatest in it's products unless it helps improve the user experience somehow without detracting from the rest of the experience (like shorter battery life). The iPhone didn't have a camera in version 1. The iPad still doesn't have a USB port, not because Apple couldn't do it, but they wanted to push the Cloud, and an experience where wireless is the way to go. This is SO MUCH NICER than having cords upon cords sticking out of an iPad and having to leave it on your desk. It's meant as a portable device, thus Apple enforces the better user experience - wireless.
I bet Apple is right now looking at how to do NFC right, and figuring out the simplest way.
