Problem is even though it looks familiar it feels anything but. I spent a considerable amount of time making my work Linux environment feel (I don't care mucht about the looks) like my Mac at home, Things like keyboard shortcuts, terminal application, spotlight, expose window movement, etc. Because I just don't want to keep adjusting my workflow between two different systems. But it's really hard to get it done completely or find a common middleground that works effectively on both systems.
