You can use ActiveSync to keep two PCs completely in agreement. YOu CANNOT
sync one set of data on one PC and a separate one on the other. Windows
Mobile devices using ActiveSync have exactly ONE set of Contacts, Calendar,
etc. If you sync the PDA with the first PC and then sync it with the
second, the data will be merged into the second PC so that everything on the
first PC will then be on the second.
