Just learned what Siri is (An application for iOS – this is Mac OS Mobile OS for IPhones).
Sisi application uses a natural language user interface to answer questions, make recommendations, and perform actions by delegating requests to a set of Web services.
It is said to work well but as I don’t own iPhone or IPad, I dunno. For sure the voice ordering applications are part of the future world, so Apple did wise to buy and develop Siri only for their platform.
