Erm? Siri is still in Beta as far as I know as it still does not work fully, and Apple Maps is also in Beta as it too is a broken and unfinished application. I am also not talking about the app store when mentioning these products as I believe I am correct in stating you cannot get Siri from the app store for one?
I was using irony, pointing out the double standard Apple applies to the App stores. Apple claims to be protecting consumers from beta software by disallowing it from third parties, but is guilty of it themselves. In reality, this means third party software (at least on the iApp store) can't be beta tested, therefore the first release could be considered a beta. One more reason to avoid the Mac App store.
