I hope, as others have said, that the new ads will be more fast-paced, but slow enough to atleast understand. I also hope that this time they show actuall clips of osx, mention that as of now there is not one single virus, and maybe some other cool tricks (show eye candy in some of the spots, some people switch just for the minimization of windows and magnification of the dock! )
