Apple announced and released OS X 10.8(Mountain Lion) to developers today. It is less of a total OS upgrade and more like refining and adding more(in my opinion needed) features to the operating system. It again(similar to what OS X 10.7 Lion did), takes ideas from the iPad and iOS as a whole, expands upon them and brings them to the Mac. You can grab it, and find out more about it from here http://www.apple.com.../mountain-lion/ If you ask me, I'm pretty excited for it and will most likely download the developer preview over the weekend. I'm actually really interested in the new security stuff. Gatekeeper seems(from first glance) really cool.
