Tim Cook announced today that OS X Mountain Lion will ship tomorrow, July 25th, for a price tag of $19.99. Mac OS X Mountain Lion consists of over 200 new features — bringing your iOS device and Mac together more than ever.

Don’t forget to prepare your Mac for the update! This means backing up any or all necessary files, removing anything that may conflict with a new feature of Mountain Lion (for example, Safari Omnibar), and backing up your notes from Stickies.
