Apple just released a beta version of its new Messages app for Mac. This app has long been expected from Apple, and as rumors hold true, its a replacement for iChat. The new Messages app will allow you to message any Mac using the Messages app, or any iPhone, iPod, or iPad using iMessage. (why didn't they just call it iMessage for mac). Currently I get an error on the download page on Apple's site so I can't download it at the moment. But give it a shot for yourself and see if you can download and use iMessage! Video coming later today...
