The launch of FCPX may already fit a business case, but from a differing perspective. I think this launch is an attempt by Apple to navigate a disruptive innovation in the face of an established professional user base that expects sustaining innovations with smooth transitions, not abrupt painful changes.
The rationale for releasing a technologically advanced product with lesser capabilities than what is needed by the core user base is well described by Prof. Clayton Christensen from the Harvard Business School in his treatise on “The Innovators Dilemma.” I’ve detailed this further in the following post: https://forums.macrumors.com/showthread.php?t=1177352
I’m not saying that this was the right or wrong move, but I am saying that what strikes many (especially and understandably here) as sheer stupidity on Apple’s part may be a bold and calculating gamble (which still may fail!).
