IOS 5 looks like it will be a very significant update and the notifications look great, but there is one feature missing that needs to be there and that's quick reply. I know this beta 1 so its still possible it will be implemented in the future, but we must do our part to encourage this. Everyone should go to apple.com/feedback and make that a request. Incase it's slipped there mind I think if many ppl ask for this it will happen. It would be much appreciated.
