Did the Drake equation thing that Slick posted, used pretty pessimistic figures (by my standards, anyway) and arrived at N=3. Interesting.

Also, note that the Drake equation was formulated to look for life that can communicate with us. As such its numbers are for our galaxy alone because the assumption is that other galaxies are too far away to pick up individual signals.

So if the question is about "intelligent live in the universe", Drake equation would have to be multiplied by the "biyyllllons and biyyllllons" of other galaxies, and the term about communication dropped.
