For the past month or so since starting back to college, I have been using both Entourage and Mail. Last year, all I used was Mail. I haven't quite figured out which one I like most. I know Mail is simple, but there is something about Entourage that I like and I just can't place my finger on it. I like Mail's smart boxes, but I guess I just like Entourage's integration with its calendar program, notes, etc. What is your favorite? This should be a nice discussion.
