I know there is much more room for improvement but it is an improvement by itself when you can ask your phone to get directions, call businesses, watch trailers, make calls, send texts and not to mention make reservations ( using integrated open table ), get game scores, movie reviews and launch apps. Now I wish it was possible that siri had the following features:
1. if we could use siri to use public transport in nyc ( can only happen with maps improving i suppose)
2. send voice memos
3. send/ receive money/ gift cards using some sort of integration with passbook
4. find prices of various things ( for example if you say i need to buy a playstation, it should show up prices near your location and maybe the cheapest price online)
I am sure other people have more to add to this
