http://office.microsoft.com/outlook is a good place to start.
Using a trial version could also help.
A good reason for me to upgrade doesn't have to be the same for you.
But I can blur out some random stuff;
-indexed search
-attachment previewer
-To-Do Bar
-improved task and calendar management
-new email editor with Ribbon support
-improved contact management options
-improved account manangement
Those are some obvious visual end-user changes. There are plenty more
visible things and even more changes "under the hood." You might want to be
a bit more specific in what would be good reasons for you to upgrade.
