Apple first released the Mountain Lion developer preview back in February, and during the recent keynote, more details about the upcoming OS were revealed. Aside from the iOS features that it’ll be getting (Reminders, Notes, iCloud, Notifications, Messages etc.), Mountain Lion will also have Facebook integration, Dictation, Sharing and the nifty Power Nap – where the Mac is able to stay up-to-date even when it’s in sleep mode. The complete list of over 200 new features can be found on Apple’s webpage here. Mountain Lion will be coming to the Mac App Store in July for only $19.99, which is a complete bargain for the upgrade. You can check out the new video trailer highlighting all the major changes after the gap.
