Enterprise. User CALs are likely to be more cost effective than Device CALs if
there are multiple devices per user (for example, a user has a laptop and
handheld computer accessing CRM) This CAL provides both read-write access to all
capabilities within Dynamics CRM and consists of both the Limited CAL and the
Full Use additive CAL combined to provide full functionality. Microsoft
