      killing Office for Mac

IMHO that would be a catastrophe for Apple: the existence of MS Office being the only reason Mac OS X (and not Linux) is an accepted alternative for employees inside many companies (including at Adobe btw).

Sorry, but CS is niche software used by certain professionals. MS Office / Exchange are used by everybody else ;)

And I wouldn't bet against Microsoft for providing an alternative to CS: judging from the experience of using Microsoft Blend, they are rookies, but they can manage it.
