I liked the honeycomb for the same reason you said, its adds some character.  Who ever put together this side by side comparison should have used the same backdrop and icons for effect.  I really hope 6.5 makes optimal use of transparency.  For example, I think apps like MSN depicted in your post would look better if they showed the background image where in this instance the color black is used.  Also, it would be nice if the screen size/resolution can handle it to show more than 3 columns.  Perhaps it does support this, I just don't know.
