I was just forwarded a great link on the BlackBerry website that breaks down the features of each different BlackBerry email solution. The features are displayed in an easy to digest chart that I found very useful. I know I have received quite a few questions about the differences between BES and BlackBerry Professional Software so this might help. You can see the original at this link:
