The only effects I used were the cube desktop, and the jelly windows when dragging. When people saw me switch apps, with each one running in its own face of the cube, they'd almost be ready to switch to Linux just to get that.

Now I run boring old Unity, though still with four desktops, and they do a sliding effect when switching, but no where near as cool as a cube.
