Mac OS X 10.8 Mountain Lion Developer Preview 4

Mountain Lion, a.k.a. OS X 10.8, marries the Apple desktop operating system to iOS features that previously were found only on the iPhone and iPad. Among them: Messages, Notifications, Reminders, a Game Center, and better integration with iCloud. It's not a revolutionary upgrade to the desktop OS, but it should please Mac enterprise users.

Apple hopes it just works

Microsoft's Windows Vista, the follow-on to Windows XP, created a huge panic in the enterprise when it was introduced back in 2007. Users couldn't understand the logic or reasoning behind the design changes. By contrast, people switching from Lion to Mountain Lion will suffer no such trauma.

Mountain Lion is not revolutionary. As with its iOS mobile operating system, Apple is content to introduce carefully engineered and designed evolutionary changes. Upgrading to Mountain Lion will be similar to upgrading from Leopard to Snow Leopard.

Though it might not sound exciting, Apple's approach to desktop upgrades does guarantee a smooth experience for users. And users' perception that "it just works" is more important than ever as Apple makes a push for the enterprise.
