But everyone would still know it's the voice recognition software that used to be called Siri, as I said they will (even if told otherwise) use it to get an idea of what the real Siri is like.
The problem I have is that they're likely doing it to drive customers to the new iPhone, and you shouldn't have to strip out functionality from existing hardware to get people to upgrade. The whole argument about them removing it due to confusion doesn't hold IMO, because they could easily fix that confusion if they tried.
I don't deny that's a part of it, I don't know. But there could be other reasons. We'll see whether the iPad 2 gets it or not, there shouldn't really be anything to stop it from getting it. (I have thought perhaps the iPad 2 lacks some specific thing required for Siri but that's pure speculation, considering it was six months ago before the iPad 2 was released and even a month or two before that when it was finalized.)
What do you mean "you shouldn't have to strip out functionality from existing hardware to get people to upgrade"? Do you mean strip functionality of the version of Siri on the App Store, if so, they didn't. It's been that way for quite a while.
Wasn't Siri put on the App Store by the company who owned Siri, and then Apple's acquired the company and then left it there for the time being?
Ultimately there won't be any solid proof until the jail break community gets to it and tries and hack Siri onto older devices and also when reviews like from Anandtech come out. When that happens, my bet is this: any devices running the A4 and lower aren't powerful enough to run it. I believe what I've read, that Siri makes use of one of the PowerVR cores in the MP2 for background noise filtering, processing speech, etc.
