Didn't even Wozniak say that Siri isn't as good as the advertisements?
Steve quoted on various news sites:
I have a lower success rate with Siri than I do with the voice built into the Android, and that bothers me. I’ll be saying, over and over again in my car, ‘Call the Lark Creek Steak House,’ and I can’t get it done. Then I pick up my Android, say the same thing, and it’s done. [...] On the 4S I can only do that when Siri can connect over the Internet. But many times it can’t connect. I’ve never had Android come back and say, ‘I can’t connect over the Internet. [...] Plus I get navigation. Android is way ahead on that.
