The only comments I've seen regarding Siri claim that Android has had it for 2 years now. If they are talking about about voice recognition to dial numbers and play songs, then Apple has had that for years as well. If Android has had conversational, contextual voice recognition that seamlessly integrates all the core apps plus external information sources allowing the user to speak naturally, then a lot of marketing dweebs in several companies should be fired because I've never heard of it.
Anyway, I can't wait to see how Siri works in the real world. If it works even half as well as the demo, it seems like a big deal to me. As in "killer app" big. Truthfully I was confused by the audience's staid reaction, I don't think understood how awesome the potential of it is.
Yeah, I sound like a fanboy.
