I appreciate the suggestion. We (as the elementary team) did not actually create the video -- rather, a (very talented) fan created it of his own accord and sent it to us.
I agree that we would be well served by highlighting the features of elementary OS which are visually dissimilar to OS X, but frankly, Apple doesn't own light color schemes and multi-desktops. The latter has been on Linux long before Apple implemented them in OS X with Leopard in ~2005. Furthermore the "dock" wasn't invented by Apple (RISC OS had it first, iirc).
I hope I'm not coming across as overly defensive. I definitely appreciate the comments and I understand that you are expressing your opinions about what you got out of the video. But, as I've said elsewhere in this thread, we're not embarrassed by our dock and multi-desktop implementation (which, by the way, actually works rather differently than any other implementation we know of, particularly with regard to dragging apps around). We're proud of them, and we want to show them off -- aesthetic parallels to OS X or not.
