The Key Feature

As I reported in March:

A year ago, Apple bought Siri, a virtual personal assistant startup that had released a very cool iPhone app. The Siri team and technology are now said to be a big part of iOS 5.

The use of Siri’s artificial intelligence and assistance technology is said to be deeply integrated into the OS for all the different services offered.

Of course, I was hearing at the time it would launch at WWDC — that obviously didn’t happen. But it was unveiled yesterday.

The one thing I’m still not clear about: did Apple hold back the Siri because the iPhone 4S wasn’t ready yet — or did Apple hold back the iPhone 4S because Siri wasn’t ready yet? Or was it neither? Was Siri always intended to be a “one more thing” feature of iOS 5 specifically for the fall iPhone refresh?

My original source who nailed the feature itself sure seemed to think it was coming at WWDC…
