Chris Breen has written a nice follow up
piece about Macworld's predictions for Leopard. The article lists the things that Apple delivered on, and the things they didn't. Granted the editors just listed things they wanted to see and not things that they were sure were going to see the light of day, but Apple did deliver on quite a few their wishes.
So, dear TUAWers, what OS X wishes did the sneak peek of Leopard fulfill and what features did it still leave you craving?
