What I'm saying is that desktops will linger where they are needed as minicomputers and mainframes do today, but the average user is better off at home with a tablet device. But that being said, Apple didn't put the iOS desktop on OS X or vica versa, they tuned the two branches of the OS for each environment, this is likely what MS should have done.
Apple is smart, with the "Magic Pad," I hardly ever use my mouse on my MacPros. Microsoft is showing the world it still doesn't get it, the two (desktop/laptop and tablet/phone) are different media and need to be developed for differently.
