It's been something RIM has been promising to bring to consumers forever now although I probably would have started with the launch of a BlackBerry Desktop Manager for Mac users first before I'd have even think about MediaSync. But that's just my opinion :-)
Hot on the heels of their Windows update of MediaSync, RIM is now offering up a "Preview" of the application for all you Mac users out there. Be sure to check it and let us know what ya think in the comments. Was the wait for some Mac tools worth it or should RIM go back to the drawing board? Keep in mind this is a preview and not final product.
