Safari may be missing some IE features like "Send Page" in the Mail menu, but these are compensated for by the fact that Services now work.
So, for example, you can mail the current selection (i.e., the URL of the page you are on, which you can highlight by pressing Command-L) by choosing Services -> Mail -> Send Selection in the Safari menu.
