Windows CE Core or Pro?

Windows CE 5.0 supports two licensing models, Core and Pro, the difference between Core and Pro is defined here - there are a number of components that are in Pro, that includes ActiveSync, Internet Explorer and other components (check the word document or the runtime licensing tool to determine which features you have) - so, how much work do you do to make sure you are keeping within the "Core" functionality of Windows CE ?
