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.

Not to mention all of those applications had a windows version. Yes, even Final Cut (at least the version they shopped at NAB).

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".

I believe Aperture was developed in-house.

Apple at that point would buy Pixelmator in a heartbeat and make its own product.
