iDeviceGuru said:Yes that's because Siri was designed around the iPhone 4s, not the iPad 2, that's why the new A5x chip is needed for Siri to work on the new iPad, other features are needed, but it's the chip that does everything that the iPad can do, such as process the information before sending it to servers.

Actually,the information is processed on the servers,there is no pre-processing before ending the info to the servers.
