I think that it's most likely they want everyone on the latest OSX for the same reasons that it's good to have everyone on the latest iOS.
Whatever they're planning, getting everyone on board is obviously an important part of that.
I think the biggest thing over the last two keynotes is the iWork update - MS have been ridicuslously slow in the one area they could have won, which was bringing Office to iOS. I'm pretty sure this is the nail in the coffin.
This seems to be really powerful. I've been surprised, during the last two demos of iWork, at the lack of oohs and aahs in the audience when things like (last time) the web-based editing, and (this time) the collaboration on live documents were demo'ed.
They don't get oohs and aahs because exactly the same thing has been possible via google docs for several years. It's impressive, yes, but not groundbreaking.
The quality of document you can get from Pages vs. Google Docs is night and day. Google Docs is a barebones office suite with an awful UI and live sync. iWork is a semi-professional ('prosumer?') home/school/office suite which now has synchronization as well.
Very true. That's the reason I've personally stuck with Pages for document editing. The ability to collaborate easily is going to be really, really great.
It's not unique, but it's still under-appreciated. The potential of this dual threat (Google Docs, iWork) to Microsoft is substantial. Besides, it's cool technology.
