Why Mac OS X Lion's Interface a Failure?

The Mac OS X Lion, which is on its way to release this week, is meant to simplify the operating system to unify with the iOS experience.

The operating system comes with more than 250 features—multi-touch gestures, full screen, mission control, Mac apps, launchpad, resume and several others at $29,99 in Mac App Store.
However, Gizmodo reports why Mac OS X Lion is not a great idea.

The OS X developers have produced an incongruent interface which doesn’t target any specific user group. It doesn’t satisfy the population seeking simplicity nor the professional users in search of OCD control. Unlike Microsoft’s Windows 8, Apple doesn’t provide varying levels of user control—a super-simple modal interface for normal people and pro-level classic window interface for nerds.

By combining Lion, iOS and iCloud, Apple has enabled Launchpad to have access to apps and the apps to have access to the documents which would all be in cloud eventually. But, Apple has made it complicated by having to click on the dock's Launchpad icon, launch that interface, and then select your app instead of just opening the app from the Finder itself.

Mission Control is an expanded Exposé merged with Spaces, which is supposed to open all your apps in an instance and they are grouped by each application. But, the way the developers mixed it, it may work for the advanced users but it may be very complicated for the consumers.

The Mac OS X Lion is fast and strong but from an interface point of view its failed to merge Mac OS X and iOS.
