My feeling is that Microsoft is much closer to a post-files world than Apple is. Apple thinks files should stay within the app, which is exactly the opposite of why we had consumer-viewable file systems in the first place. We want/need to be able to edit files in different programs. Windows 8's Contracts, combined with system-wide Share, and storing everything on Skydrive (so when you log in to another Windows 8 machine with your Live ID, it's all there) is a much more rounded vision for a post-file world, one where you have documents which are shared around, rather than opening apps then pointing at files.
