Why is InCopy CS4 offered separately from the Creative Suite 4 editions?
Professional editors are the primary users of InCopy CS4 and generally don’t require the full functionality of Creative Suite, while the designers they work with do. As a result, it makes sense to offer InCopy and the Creative Suite 4 editions separately. Designers can make full use of Creative Suite 4, while the editors they work with can easily integrate standalone InCopy CS4 with InDesign CS4 in a collaborative editorial workflow.
