Note, however, that those were all originally acquisitions. FCP was born at Macromedia and Apple purchased the product and hired the team. Shake came from the Nothing Real acquisition. Logic is from the Emagic acquisition.
I personally got royally screwed over Nothing Real purchase (we had a site license of both linux and windows version).
Chalice, Shake (and Tremor), Final Cut, Logic, India Pro... - all acquisitions followed by "Mac only from now on, sorry".
