OS X 10.8 Mountain Lion won’t be available for most users to play with this summer, but if you’d like to try out a little slice of it already, you can already download the Messages beta for Mac, which replaces iChat and allows you to send unlimited free messages to any Mac, iPad, iPhone or iPod touch through the iMessage protocol!
In our review of OS X 10.7, we wrote that Lion was the first great PC operating system of the Post-PC age, and that any future update of OS X would continue to blur the lines between the Mac and the iPad.
Looks like we were more right than we could have imagined. Apple has just apparently announced Mac OS X 10.8 Mountain Lion, which will make its first appearance as a developer preview today ahead of an official debut this summer.
