Yesterday we informed you that Apple announced OS X Mountain Lion and will arrive this summer. OS X 10.8 offers a number of new features and InsanelyGreatMac has put together this nice walkthrough video of OS X AirPlay mirroring. AirPlay mirroring allows you to transmit your OS X desktop onto your Apple TV over Wi-Fi, check out the video above. CultofMac also got their hands on OS X 10.8 and they created a walkthrough of 30 other features in OS X 10.8. You can check out that video after the break.
