My questions would be as follows:
-Regarding QuickTime-
QuickTime seems to be spreading its influence into media-using areas besides computers. Do you expect this trend to continue, and what forms might it take?
-Regarding Mac OS X-
What is Mac OS X to you? Of course, it's an operating system, but I'm thinking more in terms of branding...if you continue on the current course, you'll eventually reach Mac OS X version 10.9. What will you do then - release version 10.10 or make the jump to version 11? If you opt for version 11, how significant would the changes have to be to make a version 11 designation worthwhile - on the same magnitude as, say, 10.3 to 10.4, or greater than that?
