Apple’s philosophy is no mystery. They see computing as a collection of functions, not a range of hardware or a suite of apps. Those functions should articulate themselves differently depending on where the user is and how deeply they want to get involved. And although these functions should be re-optimized for specific experiences (the phone, the tablet, the desktop) the experience should be so consistent that it all feels of a piece.
They laid all of this out quite explicitly last year with the release of Mac OS X 10.7. The whole theme of Lion was “Back to the Mac”: Apple took a cartload of ideas that seemed to have worked out well on iOS and figured out how to implement them on the Mac. On Thursday, Apple unveiled a preview of Mac OS X 10.8, due to be released sometime during the summer. “Mountain Lion” walks the Mac another mile down that same path. It brings more of the iOS experience to the Mac. Just as strongly, it emphasizes just how important Apple’s new iCloud service is to . . . well, pretty much everything they’re doing.
