At the time Apple bought eMagic, Logic's UI sucked. It actually had dialogs that told you to "reboot the dialog for changes to take effect."

Given how well-regarded Logic is today, it must be drastically improved. I haven't looked at it lately, but am considering the bundle with Motion and FCP.

One piece of software Apple built in-house is Motion. While it suffers from a few UI gaffes, it was an innovative product that still has no competitor in the motion-graphics space.
