There is some inside chat that Apple are going to be applying Siri(the intuitive chat based operator on the iPhone 4s) to the new iPad, it will of course require some form of a connection, either wifi or if you have the 4G iPad them you will be able to access it anywhere, or if you create a hotspot(Contracts only!) on your iPhone device(3GS and later) it simply uses your current data allowance on your iPad as a portable wifi(some charges may be incurred so ask your contract supplier first.
Any views on having Siri on the new iPad are welcome, I'd love to hear back from you all. Any questions are also welcome.
All the best
