siri is the new feature of the iphone 4s .. i mean the coolest feature ever... you can let siri do some notes, reply to your texts, email, directions etc . siri knows and will be your humble assistant the moment you purchase iphone 4s. as of this moment im thinking of purchasing it, though it will be available later this year here in my country but i just cant wait to have it on my hands. i want to try SIRI.
