Why it will be hard for Microsoft to "win" the future desktop/tablet/Win8 race

Um, why? If you're rewriting it, why would you choose the others? Android tablet sales haven't exactly taken off, and simply starting over on iOS isn't necessarily easy or cheap if you're used to Windows. If you're rebuilding it for Windows 8, both tablet and desktop users benefit.
I wonder to what extent any under-the-covers code is shared between apps that run both on iOS and OS X (like Pages, for instance) and whether there's any economy of coding scale there.
