First I want to start off by saying to ArmyGeorge, thank you for your service to our country. It is brave people like you that allow us to live like we do in this country.

Now to try to answer your question, I have BIS also but would like to get BES for my Mac (almost impossible). BES allows everything to be synced wirelessly, contacts, calendar, mail, notes. There is no more cable to the BB and remembering to sync, it's just there where you are.
