David Chartier:

iOS and Mac OS X are symbiotic entities. When designing iOS, Apple distilled the Mac down to something pocketable, but the core concepts are there, such as an app-centric workflow, an always-accessible “home base” Dock, and a fierce pursuit of intuitive interfaces. After gaining knowledge and experience from nearly five years and four versions of iOS, Apple clearly felt that it’s time to return the favor in Lion. Apple is incorporating some of the fresh simplicity of iOS back into its point-and-click desktop computing platform that, at its conceptual core, is almost three decades old.

When Lion arrives, the Mac might begin to resemble some aspects of Apple’s simpler, more streamlined OS that’s designed for mobile devices. But that’s only because they are fundamentally good ideas that can polish a full-featured desktop platform and make it even easier to use, without sacrificing any of the power and flexibility that brought users to the platform to begin with.
