Just as we are chewing on the news that Apple is working on Mountain Lion, a major new Mac OS X release, the company published Messages Beta for the Mac, an early taste of what is coming in Mountain Lion. Certain code leaks indicated such an application could be in the works and now it is coming. The Messages application lets you send unlimited iMessages to any Mac, iPad, iPhone, or iPod touch user.

You can start an iMessage conversation on your Mac and continue it on your iOS device, and even start a FaceTime video call and bring the conversation. Messages also supports sending photos, videos, attachments, contacts, locations and more and it comes with built-in support for iMessage, AIM, Yahoo!, Google Talk and Jabber accounts. Apple noted that when you install Messages, it replaces iChat—even though iChat services will continue to work.
