While this may be against NDA, iOS 6 Beta is actually quite nice. If they can get real buy in from non-Apple iOS developers for iCloud, it will be a big win, but IMO it all comes down to iCloud (and probably the long term premium for the Apple ecosystem depends primarily on iCloud).
The security features in ML were critically necessary to keep OSX viable for business and professional use. 10.7 is vastly less secure than a well managed corporate Win 7 machine, and maybe even worse out of the box. (Linux probably covers the whole range of less or more secure based on exact distribution and features, but isn't terribly relevant for desktops). Which made the Google no-windows policy from a few years ago pretty funny. ML is now at parity with Win 7 out of the box, but still probably weaker in an enterprise setting due to lack of management tools.
