Apple's going in the other direction. They're merging tablet user experience into the desktop OS. Launchpad brings the iOS icon based type of launcher to the desktop. Notifications are now present and they're a lot like the notifications on iOS 6.

And if you think about it (think long term), there's gotta be a reason why they're converging. And I think the iPhone 5S is the clue.

64-bit ARM chip, integrating their mobile OS workflows (full screen apps, aforesaid items, et al) into the desktop could mean sooner than later they will have a ARM based MacBook AIR that could offer incredible battery life that the Surface Pro and even Surface RT cannot offer. And what's to stop them from converting all but their Pro offerings onto ARM? The software is the only hurdle at the moment - same issue on Windows RT.

If that's the case, Surface is indeed going in the wrong direction. Having a desktop on a product that's touted as being your "tablet" is just wrong. Metro is truly a mobile OS interface. Large, touch enabled, and finger friendly. After trying to use the Surface RT and going into the desktop, I've all but lost my religion. Hit areas are far too small, it just seems wrong without a keyboard and mouse.

Microsoft truly needs to have Desktop, Tablet and Phone levels of UI's. Desktop would include Enterprise, having Windows 2012 Server also have the Metro UI is just plain wrong.
