rue, there is some improvement. Doing these things locally and privately is definitely preferable; there are some new opportunities for people who can’t easily use a regular touchscreen UI; there is certainly a net increase in convenience.
But literally none of it is new or interesting. There don’t appear to be any meaningful changes to these features since they were released in beta after WWDC, beyond the expected bug fixes. (We’ll know more when we’ve had time to test them.)
