With iMessage & notifications, OS X Mountain Lion looks more like iOS

Seven months after Mac OS X Lion, Apple is releasing its first developer preview of what comes next for its desktop OS, which will be called Mountain Lion. Like its predecessor, Apple’s upcoming desktop OS is starting to bear more than a passing resemblance to iOS.

1 million copies of OS X Lion already sold

Mac OS X 10.7 Lion went on sale on Wednesday, and already Apple is saying this release is selling “faster than any other OS release in Appleā€™s history.” It’s also the first time Apple’s done a major desktop OS release through its Mac App Store.
