Because I use Android rather than iPhone and because I didn't attend the SHM, I don't really have a good grasp of either Nunchi or Siri, but from what I read, they sound very similar. Obviously Apple isn't going to turn Siri loose for Android phones, so is Nunchi a potential substitute?

Not quite an OS like Android, but more than an app that would be sold for .99 on the Android Market. Instead, something that would be preinstalled by a phone manufacturer, like Samsung for instance?

Ran into this article, and it got me wondering. http://tinyurl.com/78zswtq

Maybe someone who has an iPhone with Siri and who also saw the Nunch demo could clarify.
