Yes, you are correct, you can drag and drop. The difference is that it copies rather than move the file, also, the desktop folder needs to be visible which can be a problem if Outlook is covering it. MessageSave has a multitude of bells and whistles available also. If you have your folders where they can be seen and emails dropped on them and you have no need for the other functionality and you don't have a problem with going back and deleting the email that you just copied in order to keep your pst file under control then, yes, why spend the money. This program will not be right for many user, however for those email packrats it could be very handy.
