Mountain Lion is officially here. Mac users who are eligible for the updated operating system can download it via the Mac App Store for $19.99.
It follows last year's release of Lion, which was not that well received. As Chris Taylor points out in his review of Mountain Lion, the new Mac OS is a clear step-up -- and one that will likely get better when iOS 6 comes out this fall.
The divisions between OS X and iOS are breaking down, and Mountain Lion is evidence of that. For example, Apple has abandoned iChat in favor of Messages, which incorporates chat clients and iOS messaging. Game Center, Reminders, and Notes are also imports from iOS.
Social integration is also a big part of the new operating system. Twitter is baked into the system in many ways, and users can also add other social accounts such as Vimeo and Flickr. Facebook integration isn't ready yet, but it will be come fall.
Whether you've downloaded Mountain Lion or not, we're interested in hearing from you. What feature are you most excited about? Take our poll below and let us know your thoughts in the comments.
